Hello all,

I seem to have a very strange starting issue. When the bike is cold started it will run for 2 to 3 seconds and die. It will do this 15 to 20 times then it will run fine. If I even look at the throttle, the bike will stall. I've cleaned the carb so many times I can do it with my eyes closed. I know you can not dip the carb because it will ruin the gasket in the carb. So I never dipped it. This has been happening since I totally rebuilt the bike. It is so annoying. Any suggestions on what to try?

Find a friend with a nice running KDX and switch carbs. If it improves things, call Ron Black.

Replace the jet block gasket anyway.

Sounds lean or possibly you have the idle set too low. With a fresh top end the engine is pumping more air which could cause it to be slightly leaner than before. More compression could also lower idle speed so therefore require a higher idle setting.

Thanks guys, I am going yo replace the jet block gasket and then check the jetting.

also check your fuel delivery.
