I noticed on my 99ZL 440 that while on the trail if I push down (toward the ground not squeeze toward the handle bar) on the throttle the motor will cut out and backfire then continue to run fine again once the pressure has been released.


What would cause the motor to cut out??

That is the TSS, yes.
Is there wobble (twisting) of the throttle lever?
You can replace the plastic washers/shims on the lever pin.

On my 98 ZL500 I had the same issue, I just unplugged it at the carbs and problem was solved. (Do like RJ Gleason said if you still want that safety feature)
