RE: Super 331 combination
How much horsepower do you think the porting and polishing gave you. I was thinking of having that done when I get my valve clearances checked sometime this year. The head mechanic at the dealer said it would give a very good increase in power and would also have to rejet. I also have the 300 cc upgrade.I would love to test ride your bike, too bad you dan't make it to our northeast ride. My bike has a good power increase with the 300 and muzzy, I could only imagine how yours is with the 340, cams, port and polish and pumper, sweeeeeeet.

"i wouldn't be comparing it to a DRZ400 "
Honestly, I'm not sure what we should compare it to other than the stock KLX. There will always be faster and slower bikes, even among the exact same species. Iowa's point is well taken, about the dollar and skill investment required to upgrade the bike's performance. Of course people have been trying to squeeze as much "go" from whatever they rode or drove since the beginning of time. I'm pretty sure that performance upgrades are at least the second oldest profession.
My point in the comparison was that for about the same money we can have a bike that might perform considerably better. I have never ridden a DRZ 400 so maybe that was a bad choice. Hmmm? Maybe we should compare it to the 450XC...Just kidding Brian. Or not? Depends on what we're after.
No. My idea was to get the best bang for the buck and to sample some of the skills of the aftermarket. By doing so, we learn of alternatives to simply doubling our investment to get a faster bike. So far, the operation is more successful than I could have ever dreamed. The shops I used, many of whom you have already done business with, know their stuff. This engine is mechanically very quiet. The Muzzy with quiet core isn't bad and is light. What is not to like? It still looks as cool as it did in the showroom too.
As somebody mentioned, it really is a wolf, or perhaps a cheetah in sheeps clothing.
Whatever it is, it's a ton of fun.
I plan to ride it in the Hillbilly dual-sporttour in Eureka Springs Arkansas next weekend. If any of you can join us, look me up. I'll be on the green KLX. Can't miss it.
Here's the link to the ride for anyone who might like to come.

Bill (Blue),
That message was intended for Bill Dragoo.Your wife's bike doesn't have a 331cc kit and Muzzy exhaust, does it? If so, then I'm interested in the jetting in the TM34.
I don't think that it does because you installed the carb that I got from you in your wife's bike for testing, you installed a #125 MJ for me.
What kind of jetting did you install in Bill Dragoo's carb?

Anybody want some snap and lives in the PNW you might want to contact this guy. He has been at it a while and was into all the ceramic coatings and slippery bore coatings many years ago. I had a street port and coatings done on my Honda 541 single. It worked great!

RE: Super 331 combination
To answer the jetting question on my "Bill Blue TM 34," I am running a 135 main and 37.5 pilot. Idle screw is 1.5 turns out. Needle is second slot from the top. It runs pretty clean on these settings with only a little backfire at decel. Not much though. The spark plug is a nice, coffee with lots of cream color...a little soot around the rim. I expect tofine tune it some, but it shouldn't need much. The dyno will tell.
I could only speculate about how much the head work alone would help, but my guess isthat it would be very noticeable. Luke enlarges the exhaust ports some, polishes both inlet and exhaust, then blasts the intake ports to give a silky finish for better mixing. The port split is knife edged, no kidding, it's really sharp, so don't go noodling in there when he gets done. He also relieves the area around the valves which improves flow through the combustion chamber and lowers the compression ratio about a half point. It would have been 13/1. He leaves it at 12.5 which works well on pump gas and is a lot better than the 11.3/1 stock (If I remember the stock ratio correctly).
I think the cams are a good fit with the head work, but you and your budget will have to make that choice. Each part of the job complements the others, but also stands alone very well.
This is all easy work for any of you who are doing your own upgrades. If you can adjust your valves, you can do the whole deal. Just be careful when disassembling to mark TDC and cam position. This will make reassembly much easier.
I'm sure a good shop wouldn't charge too much to do it if you went that route. I haven't asked.
Compared to the loss of selling our bikes, not to mention the difference between that loss and buying a more high strung or full-race bike, I'm thinking this is a bargain. But then I really like the handling, weight, streetability and even the looks of the KLX.

RE: Super 331 combination
shadetree, I remember seeing oversized intake valves on the webcam website. I was wondering if you had them put in when you had the head work done. If you didn't was this talked about by the webcam rep. or the person that did the head work about putting them in? And if it was talked about and you didn't put them in why not.
