is it a automatic clutch such as electronic shift
No, it wont.
Get a new exhaust, you probably want to look at FMF exhaust but if you get one too big you might have to get it jetted or it wont idol
its broken !! take it to a mechanic
rear end is no good
It might be the brake pedal switch
Wont shift while engine is on? Is it an automatic or a manual? if you put more information I can put a more reasonable answer.
The four wheeler will run for a few seconds then just cut off and it wont have near as much power.
Push it off a cliff.
Check to see if stop lights are working - same fuse controls both shift interlock and stop lights
Because your shift solenoid is dirty and needs to be cleaned out with a carburetor cleaner.
why my kawaski 300 4 wheeler back fires and wont start
replace the shift cable
