2010 KLX250S Stalling Problem!
I've got a problem with my 2010 KLX250S; It keeps stalling on idle! Now I'm sure it's something to do with the carb, I'm just a matter of finding out what.
The strange thing is, it doesn't kind of... Die out. It seems to idle okay, then bang, she just shuts off. Also, it seems that I have to give a slight bit of throttle when starting without the choke.
Bike has ~15,000Km (9,000 miles) on the clock. It's an Australian version (I believe the carb is slightly different?).
I've played with the mixture screw a bit. Like I said though, seems to idle okay usually. Side note - How the hell do you get to the thing without virtually removing the carb?!
Took the carb off and cleaned it out. No difference.
MODS! It has an FMF pipe and the airbox cover removed. I've also installed a Dynojet kit, which included a larger main jet (can't remember what I put in exactly), a new slide spring and needle.
I haven't changed the pilot jet! I've heard going to a #48 can make a huge difference in starting. Maybe this would help?
Plug is relatively new.
The only other thing I haven't even looked at is the float height. Maybe it's set too low running out of fuel, or something? Thoughts?
I can upload a video if that will help.
Any ideas would be greatly appreciated. Thanks in advance!
