Arrow Enjoy the little klx that could

When I bought my KLX, I collected these links to articles to do the job. When I finished the modding of the KLX, I posted all the info I had in my bookmarks to this thread.

It is time for others to take control of the KLX FAQ and make this thread the place to go to find info fast. FAQ hit 20,000 hits, so it is being used. I am glad this thread is still short, as it is easier to find info with just facts.

I contacted IDRIDR and he said he will post more here and I encourage other to join him.

42/13 = 3.230 or 3.230 to 1. Meaning for every 3.230 revolution the front makes the rear sprocket will make one full revolution. Or 3.230 divided by 3 (Stock Gear Ratio) = 1.076 or 7.6% gear reduction over stock. So if you are going 40 MPH at say 5000 RPM with stock gearing. With the 13 tooth front the engine will have to be running at 5380 RPM to go the same 40 MPH. 5000 RPM x 7% = 380 + 5000 = 5380 RPM.

So it is a ratio on the RPM change not a set amount like 500, but close.
14t at 60= 7,000 RPM then 13t at 60= 7,532 RPM
14T at 70 = 8500 rpm then 13t at 70 = 9,146 RPM


more good info

Fact of life.


Then we swapped bikes.

Oh.

Oh, I see. Yes... hold on, what was that? Oh yes, the clouds part, angles begin to sing, and rays of heavenly light begin to surround the KLX.

Mr. KLX: Whoops? What whoops? Let my long legs simply turn these sneaky fork benders into a happy afterthought. Moguls? A simple bump, nothing more. Oh, and, would you like some air with that? Really, no need to slow down; just use caution about where you land that front tire; but not too much, I'll save your butt and prove my superior engineering will almost always get your inexperineced and overconfidenced behind out of trouble.

Me: :drool:

It soaked up so many things I was sure this was really an Imperial Speeder-bike. You know, like in Return of the Jedi.



Lots of track guys say things like "I just thought and it went". I understand that, and it applies here. It is strange to thing of precision in an environment like a dirt track, yet that's exactly what the KLX gives you. The brakes are precise, the engine manipulation is precise, the throttle and clutch are precise. It doesn't clatter, chatter, or otherwise give you any impression of being a lot of bits strung together in hopes of becoming more than the sum of its parts. It feels more akin to being carved from a solid piece of something... something fun and something fast (at least offroad). It was heavier than my TT-R, of course, and a great deal taller, but oddly, unless I was in a situation that called for an off-camber stop in a ditch, it was at least as easy to control. When in motion, more often than not, it was easier to control than my little TT-R.

I wheelied it. I squared off corners. I powerslid. I throttle slid. I locked 'em both up and prayed. I whooped. I jumped. I landed.

It was a fantastic ride. It still proves to make me grin and, I hate to say it, but I covet that bike. I want one. I want one badly.

Road:

The day was bright and clear, and just a tad crisp. I found myself headed out into the twistier parts of Iowa (yeah, I know how that sounds, but you'll have to trust me here). I decided to stop and call my buddy; maybe he'd like to join me. Even though the XX is capable of stomping the ever living Kawasaki green out of his little KLX, I really enjoyed riding with my friend. Oh, and forget the fact that I was hoping he'd let me trade bikes so I could give his little machine a good on-road summary. Shhhhhhhh...

After about 60 miles, I asked him if he wanted to trade steeds. He's a new rider, but he's also a cautious guy, and the XX is a rather forgiving machine so long as you're not being a complete ****** with it. Besides, I was insured. Since I was the guy who had lent him all manner of bikes, and encouraged him to ride, he was gracious enough to oblige me.

Here's what I expected: The bike would get blown around. It would be very vibey. I expected, certainly, that the top speed would be very lacking and that getting to legal highway speeds would be *yawn* boring. The ride, of course, would be similar to the KLR, if not more Caddillac-like due to much longer suspension travel. Funny how things can be different than you expect, eh?

Is this bike a great road bike? No, of course not, but it does better than it lets on. It, my dear friends, is a dual-sport bike, and as such it must follow the cardinal rule of its pedigree and be an exercise in compromise. I would love to have been able to flip a switch and have the engine do a Transformer dance and turn into a 1157cc fire breathing powerhouse, but alas, no such switch exists on this bike. I'm not sure what the engine produces in the way of horsepower, and it is probably for the best, but I'll suffice to say that it is more than enough offroad for most anyone, and enough on the street to stay easily with traffic up to legal speeds. Faster cars and most other motorcycles will have their way with you, but you can smile and know that the sky's the limit when you decide where you want to go for the day.

In mixed traffic, the bike does well. You have great visibility, and the stiff chassis makes the bike feel extremely nimble; even hyper-responsive to your input below 55mph. Above this speed, the bike becomes a bit twitchy due to the steepness of the geometry. I'd strongly recommend a steering damper if this were a highway bike. The odd thing, however, is that even once the bike begins to oscillate (as DS bikes often do) it wants to settle right back down; especially when you go 'light' on the bars. It, my friends, is smarter than you in this regard. Still, I stand by my suggestion of a damper; it will only make things better in most any circumstance. But, stability aside, how does it compare in 0-60 times? I know you are asking the question, and I'll answer as best I can: it does fine. I had no problem pulling ahead of traffic, but don't expect much when you're at 45mph and you want to overtake a car doing 10mph faster than you; especially on an uphill grade. Let's just say that if you're in hill country, and my weight or higher, you'll find that 70mph is quite attainable and maintainable, but not much more. In flats, with enough room, and indicated 95 is about all she has in her, but that's not really the point of this bike, now is it?



The 6th speed is a necessity. It allows the other gears to be lower and pull the bike around with its rather smallish engine. I never really felt it to be lacking, and could easily loft the wheel in first on power alone, and ride into other gears up on one without much fancy clutchwork, etc. It is an astonishingly controllable bike, and the transmission is a nice, positive feeling unit that enhances the feel of control one gets from riding it. The gearing is predictable and never left me feeling that some gap was left in the powerband due to wonky gearing.

At speed, to be more specific, at highway speeds of 65-70mph, the bike does emit a buzz. It is not the deep tissue massage of the larger displacement thumpers, but more of a tingling buzz as the little single cylinder leaps to and fro at an amazing speed of up to 11Krpm. It is quite smooth, in fact, weridly smooth, at 'around town' speeds. The smaller displacement does much to make up for a lack of heavy counterbalancers in the engine like the KLR uses. As such, is more snappy and peppy than its bigger, and older brother. It revs quite freely, and is a great plaything. The exhaust note is quite nice; especially for such a small bike. It is quiet, and I like that. When offroad I appreciate the feeling of being a little less obtrusive in nature, and when highway riding I appreciate its consideration of my hearing. A nice mix.

The brakes are more than adequate in any situation. All the little bits worked well, and didn't leave anything to be wanting that I'd given note of. I must keep returning to the instrument cluster; it is simply pleasing to look at, and tells you what you want and need with no gimmicky complexity, and all the shapes are comforting to the eye. The colors are nice and bright and the contrast of the numbers is nice.



Lots of Japanese bikes, especially in the DS spectrum, seem a bit... well... cobbled together. The KLX is having none of this, thankyouverymuch. It feels very well built, and very solid. For you bicycle riders, it is like going from an off-the-shelf steel Huffy to a near top-of-the-line Cannondale. Yeah, maybe they both have similar function and similar bits, but one is a world away from the other. One of the ways that set this aside, and maybe the defining factor in this is the bike's suspension.

I expected it to roll down the road like it was on a cloud. I was wrong. The suspension, while not harsh, gave incredible feedback. It was not sloppy, mushy, or spongy. It was tight, precise, and firm. I couldn't quite get my mind around how the bike could be so smooth and plush offroad, yet give such good feedback (even over small imperfections and road surface debris), but it does. There was no appreciable fork wandering, thanks to the beefy USD tubes. There was very little chassis flex, and the bike put into corners amazingly well even on nearly offroad-only tires (big lugs!).



I put nearly 300 miles on that bike, with about 135-155 miles per tank and never found a point where I wasn't enjoying the machine. I'd like to have a bigger tank for roadgoing, but for offroading it provided plenty of entertainment.

It did get blown around a bit. Hey, it's a light bike with steep geometry!

So, the reader with at least two active brain cells to rub together can tell I really enjoyed this bike. It shines where other larger bikes fail, and in surprising ways. I was skeptical that such a small displacement bike would fit so well into such a broad spectrum of riding. I think this bike is, perhaps, one of motorcycling's best kept secrets, at least in the Americas. This bike has been around for a number of years overseas, and as such has quite a few performance upgrades available to include a big-bore 330cc kit which is sure to enhance all the positive aspects of this machine while nearly eliminating some of the not-so-positive ones (though I can't for the life of me remember what they are at the moment). If you haven't considered this bike for your needs, please do. If you disagree with me, by all means share your stories, but at least take the time to note how many roles this bike can fill, and do so for a very small entry fee.

The point of the fender is about 3/8" from the edge of the tire. It's moved to the (if we were talking about cars) passenger side. What the heck is up with this guys?

Loosening the clamps and re-aligning the front wheel is the correct way to fix this,(Use the correct torque values when tightening the triples) but out in the woods you can use the handlebars to bang the side of the front wheel against a tree which can rotate the tubes back into place.

To long and and the bike wants to fall to the right after getting my weight off. To short and it will easily fall left.

Just right is difficult to find and set with a cut and weld method.

So - an M10 coupling nut fits nicely up into the cutoff kickstand. A M10 nut with a M10 hex head bolt bottomed fits nicely in the bottom piece.

A little welding, some Locktite and here it is.

About 55 cents worth of dimes and pennies shoved into the spring at max extension makes it easy to remove and replace.

Note - Some pictures show one lock nut and some show two. I settled on 2 to use as a locking nut. Only the very bottom nut and the upper coupling nut are welded in.






Moto Pro KLX250S Suspension Upgrades
I found parts needed to rebuild my factory rear shock & front forks from Moto Pro.
I am not using their products currently but its good to know where to find parts if needed.

I am still riding the KLX351 I will continue supporting the KLX250S & SF.

Some quick facts;
Bill has sold 377 of his 351 kits!
Going from a 250 to a 351 is a 33% power upgrade!
On this upgrade with a stock carb your go up 2 on the main jet and 1 on the pilot. I am in GA and have a 132 main and a 38 pilot. I have a M4 exhaust, the air box lid removed, and a Uni air filter.

I spoke with Bill a few times and he is a good guy and I would love to ride with him some day!

Trouble spots are few. I am lucky to have my riding buddy is my neighbor and that he loves to get his hands dirty. He also has almost every tool made!
The carb on the KLX is a bare to remove and re-install because it is a tight fit. I removed the metal bracket on the top of the carb that routes the throttle cables.



My engine bolts where odd because there was 4 bolts and 4 washers but the front right bolt had no washer installed from the factory and the one across had 2 washers!

Bill's 351 fits perfectly and adds power for wheelies and hills. I have had a DRZ400s and my KLX351s feels better.

I'm from Belgium and we also get the EFI model here. <3 So to answer some of your questions and recommend some stuff:

  1. First off, don't upgrade untill you've had the bike for a few months! Especially if you are tight on cash. Some stuff might not be needed.
  2. For example the seat and bigger tank: If you only plan on doing short rides arround town or the odd camping trip then try out both first. I've ridden 2+ hours on mine with the stock seat and wasen't soar at all. And with a full tank I got arround 180+km's. So upgrading was not needed.
  3. As for the rack, how about looking for suppliers in the EU or even your own country? Have you asked your dealer if he can get some of the items you want? (Remember, within the EU you don't have to pay import tax, but outside you do...)
  4. An essential upgrade on the EFI model is to get rid of the 110 km/h restriction. This is a free mod and is explained HERE.
  5. You can also remove your airbox snorkel for a slight increase in power and a deeper sound or get a bigger one like THIS. (Picture below shows difference between, from top to bottom: no snorkel, bigger snorkel and stock.)

is it possible to swap a klx 250 engine to a klx 300 frame?

What does it need? Imo, a skid plate, a dynojet kit/air filter, hand guards, a seat of some sort, and some real tires.

The dynojet kit improves throttle response considerably, and in many cases will improve fuel economy. I like to add a twinair filter (and use notoil filter oil), and many like to add the kdx snorkel in place of the stock snorkel ($20). The stock seat is awful; the best bang for the buck is the seat concepts one ($179) that you "assemble" yourself. And for tires, if you're going to be riding off-road, we've found the kenda k760 trackmaster ii's to be good for their price (under $100 for a set). If you're just going to ride road mostly, the stockers are fine.

The first time you drop it, you will likely lose a mirror and at least one turn signal, so be prepared. Hand guards will protect your levers. I like barkbusters, but if you have the money to spare, the hdb (highway dirt bikes) guards are really nice, but pricey. Look at double take mirrors once you break yours. You can get new turn signals on ebay from china super cheap (order several sets so you have spares).

The 80's klx were completely different, so also will not take accept the 300 parts.

Good info.

Hopefully this will become a useful reference for everyone and will stay updated. When I owned mopeds there was a very good community and a very extensive spreadsheet, it was super helpful. The spreadsheet is fully public and editable to all so please feel free to add more than just your info but also be careful when making changes to the main structure of it.

Last year I drilled the starter jet and installed a DJ kit (stage 2), but that did not seemed to help that much.

Things ranging from an unusual needle/seat interface, a stiff float pin interface, abnormal buoyancy in the float, etc. can all give a different "real" fuel level while you can still get the correct listed static float height. It's not common, but it happens. Glad you got it to respond to your satisfaction.

I realize it is perverse publish weight with a full gas tank, therefore penalizing the manufacturers for providing additional gas capacity to a stock motorcycle. As adventure riders, that's one of the things we are always screaming about. Unfortunately, weight with a full tank is the only number I can find that is comparable. Wet weight with an empty gas tank would be the most fair comparison, but it is hard to find.

Motorcycle Consumer News is a helpful resource to have all those weights listed together, but the MCN numbers are consistently lighter than the weights from other sources, and I suspect they are using the half tank of fuel method for determining wet weight.

One of the frustrating things about this project is the reminder that the magazines don't take dual sports very seriously. For example, the KLX250S is one of the more significant additions to the dual sport world in the last few years, yet Cycle World treated it with a one page glossover and no spec sheet at all. The TE610 has been featured in several articles, including comparisons of sorts (Anywhere, Anytime, May 2006 Cycle World, 310 lbs dry) but never with an all up weight. I'm hoping that will change as the new models hit the floor this spring. But it's not like the good old days when Art Friedman was editor of Motorcyclist and dual sports were part of every third issue.

Since dual sports typically hold between 2 and 2.5 gallons, I'll note those that are carrying 3 gallons or more, and readers can do the math if they want to see where a bike might rank with less gasoline. (6 lbs/gallon)

13/49 is very low gearing. For me, as a noob to dirt and steep nasty rocky climbs a year ago, it was perfect. After a few months with this setup, including first trip to Moab and a bunch of gnarly stuff, graduated to the 14, then 15. Several rides ago, on a planned excursion to some difficult stuff, the 13 went back on, and good it did. And low gears are better in snow.
With the 351, the rear will go back to stock 42 or a 45, and I'll continue to use the 13/14/15 setup up front depending on the ride.

-KLX has way more aftermarket parts and tuning possibilities, big bores and such.
-KLX has more ground clearance
-KLX has fuel cap with a hinge(honda cap drops off).
-KLX has two sided full chain guide, Honda has only outer side chain guide.
-KLX jumps better(lighter, better suspension)

Some argue that honda is better because it has EFI, well in europe the KLX has EFI too.

But what you gain in height you will loose in low speed shock absorption by being a tad to firm, by over winding the pre-load. This will work in the short term but when all your fillings have fallen out & your @ss in numb, spend 90 bucks on a firmer progressive spring!

I did exactly that for nearly a year (teeth & numbness etc) & then gave in & got the new spring which was firmer at high speed & had the bonus of a taller ride height with better plusher low speed shock absorption with way less rear end sag.

EDIT: Forgot to mention playing with your compression & rebound clickers on the rear shock! They really help with sag & ride height as well.

Wink klx250s FAQ

All cool white, probably the closest to the factory color back lighting.



Cool white on the speedometer and green on the tachometer. Side by side comparison.



Or all green.



I also swapped in LED Lights on the brake/tail light, license plate light, high beam indicator, and green neutral light indicator. I'm sure I freed up some amps considering all of the stock bulbs listed above drew about 52 watts. What color lights for the dash do you think I should go with? Thanks, Fred.

i just keep amping this one.
yes, i've put some $$ into it but i don't regret one cent, and i've spent a whole lot less than the guys buying and selling.
i know this bike like the back of my hand at this point -
and its so incredibly reliable i don't want anything else.

now with 351 and full suspension rebuild, its a beast in the woods.

But I hated to go to the effort to do all that without being positive, so I found another solution:

Coat hanger!




I pinned the KACR in the run position, shoes full out. A coat hanger had the right size wire, a U bend with a 41mm straight in the middle, stick the ends throug the holes, bend the ends up and trim - No KACR operating anymore! :clap I can see if the bike starts fine without the KACR with the fix being a wire cutter and replace spring away. Now I can do the cam mod and undo it if I don't like it, no pressing things apart.

I also didn't like the way the electronic speedo wire hung out ready to snag, so I did a number there too.



Drill and zip-tie along the trailing edge of the fork protector. I tried to put it behind the guard, but was concerned about the slider coming down and damaging the wire if the forks bottomed. I still may make a small aluminum shield at the bottom to avoid snagging there too. I just don't trust letting it hang out there when riding through any brush or such. Just the perfect opportunity to rip the wires out.

I reworked the carb by the following, plus the Marcelino Cam Mod and disabled the compression release. That information is pretty common knowledge as a fix for the stock jetting, no idea who did the ground work for it.

16009-1912 Kawi Needle-Jet, N1TC
92037-1401 Kawi Clamp, Jet Needle
92143-1667 Kawi Collar
Needle clip slot 2 down from the top
92063-1069 Kawi Main Jet #125 or 92063-1074 Kawi Main Jet #128
92064-1108 pilot jet #40 Air screw at 2 turns out to start
drill the slide vent to 7/64ths

Airboxsnorkel (14073-1577) high flow KDX unit


No real tricks. I did also add a Dial-A-Jet to take up the slack in the jetting variations by temperature or altitude and such.

I was surprised at how quickly it fired up compared to the stock set up the first time I started it up after doing the mod and the carb. No need for any compression release.

My bike wouldn't hesitate under full throttle, but would under constant throttle around and above 6000 rpm. Pull the choke and it went away. I had a shimmed stock needle and went to the KLX300 needle in mine. Point is the choke (enrichener) may give you verification it is lean or not.

Heck some of the guys with the KLX650s have taken them off their cams too, but that bike turns so slow I'm afraid mine wouldn't start. I'm thinking the 250 should be no problem though.

Mild steel is arguably the better choice for these shifters as they are more maleable and tend to damage the shifter shaft much less often than super stiff shifters in a crash. The MSR version can easily be tweaked to be closer or further away from the engine cover to suit your preference. The stock shifter is way too short for most people with normal sized feet IMO, and they tend to suck if you wear actual off road dirt bike boots. The MSR XR650L shifter is stiff enough without being too stiff. It can be bent back into perfect shape with a vise and wood blocks when back home, and you can usually bend it back in the field to finish the ride.

Amazing how many parts cross over. Thing is on some things you have to do some sleuthing. If a rotor fits multiple models then those hubs have the same pattern. Differences may be in finish (color or bare) or machining for speedo. You can learn what hubs are interchangeable - you'd be suprised. From there it might require actually seeing and measuring a part.

I use it for my own bikes, questions people in forums might have, and for my cam chain tenisioner sideline. I find one tensioner body fits 263 year/models of bikes, because they all use the same gasket. There is a general number for an item type, then a true part number for a model that appears on the package of the part and the diagram list. I honestly don't believe there is a simple method to track Kaw part numbers, like there is for Honda and Yamaha. Honda's middle three indicated a specific model on which the part first was used, if I remember right. Oddly enough, though, they have cases where the same basic design part is made under two part numbers - like some certain gaskets I've bought.

Good stuff, book mark this site, you never know how it will help.

Any guesses as to how and exactly where the overflow bottle on the Japanese farkles page has been moved to? It looks like there's some sort of universal bracket that's been
used to move it above the engine.

I've blown the pics up larger but it's still not that clear. I think it's been re-oriented side to side instead of front to rear as the original was.

Could come in handy when I try and fit up the CRF250 dual mufflers
