HELP!! Troubles with my KTM

goodstuff84 · #1 (**permalink**) 03-30-2008

i dont know a whole bunch about 2 strokes so figured maybe someone could offer some helpful advise, i have a 91 KTM 300exc and it starts fine and idles ok when its cold but it always bogs when i crack the throttle, even if the motors already revving, it bogs then revs, and seems to pull real hard. and also when it heats up it idles really high, and if i rev it it will stay revved up unless i bog it with the clutch, then it comes down but still idles higher than it should, any ideas?? any advice would be great! thanks

Gotta agree with that. Sounds like you need to hit the tools. Check around the intake, the cylinder base, behind the stator, ect. You've got a leak somewhere.
