Message: [QUOTE="rmc_olderthandirt, post: 1363575, member: 68872"] It is common for a dirt bike to have difficulty idling with the transmission in gear and the clutch pulled in. What happens if you rev the engine up a bit, pull the clutch and then drop it in gear? I would expect a small lurch but then it should settle down. Dirt bike clutches work in an oil bath and have very little clearance between the plates. The oil, especially when it is cold, will provide some amount of fluid coupling between the plates, also known as "clutch drag". A bike that may idle fine in neutral may not idle well in gear with the clutch pulled in. If your problem is actually clutch drag then I would expect it to improve some when the engine warms up and the oil is thinner. You can also improve the overall situation by running a thinner oil.
