I nominate the "CandyAss Camper" for president!

that was just abit off topic. lol but the man knows his machinery.

 

And no, you shouldn't do anything to it. Apparently your carb is in optimum tune, your KACR is operating just right, and what ever other alignment of stars that occurs to provide the proper starting for these bikes. The starter jet drilling is only necessary on those bikes with cold hard start symptoms. I'm still su****ious of the KACR being a large contributor to this issue.

 

Thanks TNC. Your reply is much appreciated.

I will second that.

 

Removing the seat? I'm confused.

 

I drilled my starting jet, and it still does not start right at times. More often than not. When it does that (not start), I shake the bike from side to side & lean it way over both sides and try again. That seems to make it catch. I'm thinking that little dance gets some extra past the needle valve & up into the carb body somehow - sort of a mini flood.

There is something not quite right with some of these bikes, I think there is inconsistency in the KACR setup from bike to bike. I have no way of knowing this for sure, it's just a hunch - I have not investigated. If I would really get with it, I'd check compression during cold start. Actually, it would be nice if a bunch could do that, both good starters & poor, and post results - it might help shed some light. But I have come to the conclusion that the drilling of the starter circuit is a patch work fix that still might not fix it if the issue is too far astray (e.g. the KACR timing or lift is out more than others). Maybe drilling a bigger hole than 0.018 would be needed in some cases (like mine), but I'm a bit leery of doing more drilling, and I feel it's just a bigger bandaid.

 

So does one take out this starter jet and then drill it? Or do you drill it in place and flush it out when dun?

 

Maybe your fuel level is too low.

 

The jet is pressed in, so you have to drill it in place.

 

IMHO the problem is not KACR related, it is not starter jet related, it is battery related. I've owned my 06 since 09 LOL. I had issues cold starting just like everyone else. Until I bought a battery tender and kept the bike plugged in 24/7. I do run it out of gas when it is going to sit for more than a few days. But I havent had a single cold starting problem since I started leaving it plugged in.

To prove my battery tender theory wrong or right, all one has to do is hook up jumper cables from the klx to a car or another battery and try to jump start the bike STONE FREAKIN COLD. With choke on and 0 throttle.

I see the same issue with cars, a car battery can crank the engine fine but not have enough "energy" left over for the ignition or fuel injectors to fire.
