Hi people,
my 93' XR250L is able to start and idle. When the engine cold, the bike seems normal enough, but after warming up, the bike stutters very badly when ridden with partial throttle.
When not in gear and reving the bike, it stutters badly when I twist the throttle too quickly, but seems alright if I twist it slowly.
This symptom appeared after I attempted a top end rebuild. I have checked and double checked that everything was assembled correctly.
Does this sound like an air leak anywhere? or a jetting problem, or.... Anyone has any ideas?
Cheers!
