The power commander is around $450 but looks like its in stock,, but it not a preloaded tune. I'm not familiar with it, and hoping someone out there has already figured out some tunes

 

Yeah, I know about those. I'm not getting one. Way too much money.

 

I like partzilla.
They have good customer service.

 

Hello all,
I need a little help from the group. I just did the PAIR and smog delete on my 2023 KLX 300S and now my bike won't start. I've done everything I can think of to track down the problem:

I am getting spark, pulled plug and cranked to verify. Plug is wet with fuel but does throw a spark.
Battery is good and it cranks normal speed
I smell fuel, so it's definitely not a lack of fuel
Fuel pump cycles as expected when I turn the key on
Brand new air filter
No change with fuel cap open, so I don't think it's a vent issue
Both of the nipples on the front of the airbox (PAIR and smog) are capped.
Red nipple on bottom of tank is capped
Blue nipple on bottom of tank has new vent line routed down with other vents
Smart Moto block off plate and resistor installed per instructions
I have checked every electrical connector I can find on the bike and I can't find any that are loose or any damaged wires.

My current working theory is that when I was messing with the gas tank/smog/PAIR I somehow flooded the engine and fouled the plug. I'm going to get a new plug tomorrow and try it out. Does anyone else have anything I can check?

I got the bike in November and then it snowed and then I broke my foot so it still has zero miles on it. I've been using the time while I can't ride to get all the mods I want done...and now I have a new bike that doesn't run. This sucks!

No spark?

If it's a new bike, changing the spark plug won't make any difference. Hit the end of the spark plug with a propane torch to dry it out and heat it up, then see if it works.
You can visually test the spark condition by connecting the spark plug to the spark plug wire, but not screwing it into the head. Instead leave it outside the head but in good contact with the head so it's grounded. then crank the engine over and see if you can see a spark.

If that indicates no spark. try checking things like the kickstand switch, the kill switch, the clutch switch, and the tipover switch.

 

I have spark, confirmed by the method you mentioned above. Do you remember which port or ports that you plugged on the bottom of the fuel tank? The one with the red dot next to it dumps fuel if I tilt the tank at all so I capped it off. The one with the blue dot doesn't leak fuel even with the tank all the way on it's side and allows air flow in both direction so I think that it is the normal vent. I also capped the nipple on the throttle body and both of them on the front of the air box.

I honestly can't think of what it could be. FML

I believe you will need a return line from the FI to the tank, if you only have one line, I suspect that may be your problem.

 

I hated that huge gaggle of hoses under the stock tank, so I replaced it with an IMS 2.7 gallon tank. It has only ONE hose out the bottom, the fuel hose. And the tank simply vents out the cap with a tiny one way valve that keeps fuel from being sloshed out.






My year round gas mileage averages 80 mpg so the tank has an effective range of 200 miles.

 

So....let me tell you a story about how smart I'm not. You know those plugs they sell that you can put in the exhaust to keep water out when you wash your bike? Well, since I'm not currently riding my KLX due to injury and winter I thought it would be a good idea to put the plug in to keep critters out of the exhaust.

I'm sure that y'all can figure out the rest of the story.

 

Well, I would like to know what kind of vermin you get that hang out in your exhaust pipes. I would be more worried about them getting around and eating the insulation off all your wiring, that is more common. But maybe you have bats?
