I have a new klx250 sf that will die after a fast stop/endo situation. I have megabomb pipe and powercore 4 silencer and a k&n filter, I have a dynajet stage 2 jet kit. The bike runs great in all situations but the fast stop

 

Are you partially bumping the kill switch with your hand?
Dan

 

Stop doing that!!! LOL

 

What is your idle speed?

CV slide moving? Do these bikes have a kickstand safety switch?

 

Yes - good call.

 

Good guess. I could see a person's heel rotating down during an endo and pressing on the kickstand. That's why I always remove the switch - my heel makes the bike cut out when I stand on the pegs.

 

I took front endo meaning like a stoppie. So when the rear slams back down.... I've had both issues with my old DR350's.

 

You need to practice your stops.

 

It acts like it is choked, if it sits for a miniuet it will be ok. If I stop and hit the gas is when it dies.

My Idle speed is about 1500rpm
