I have a 2005 yz-250, eric gorr 295 kit, bike has been a dream until today. Now it has a surging thing going on rather a miss is happening, not a miss in the engine but a miss in the drive train somewhere but it is only in 5th gear and it is very consistent, it happens like clock work at constant intervals regardless of RPM or throttle position? The best way to describe the feeling is if you were to go at a constant rpm in 5th gear and were to fan the clutch. Any ideas?
