piston rings
- Thread starter BLASTR
- Start date
for one if it was piston rings it would be difficult to start. wouldn't make it over rev. sounds like sticky throttle or a carb problem if it revs too high. piston rings make bike or quad dull to kick or if there gone the bike won't start.
thats a sure sign of a dirty pilot jet or an airleak < which could come from any number of places...carb, carb intake boot, intake gaskets, head or base gasket, bad crank seals, leaking case halves or even cracked cases
worn piston rings are known to cause hard starting
i wouldn't touch that without doing a leakdown and compression test to verify the problem
or unless it was dirt cheap and you have the funds to put into possibly rebuilding it

or the carb is stuck
bring a compression tester with u and see what its at
should be between 110 and 130 stock
