Hi, Problem with the gearbox on my sportster, when the engine gets warm i'ts difficult to shift to the next lower gear. I can't go further down with the gearshifter I have to release the clutch a little bit and then it sounds awful as the cogs grasps into each other.Sometimes I have a neutral between 5 and the 4 gear and 4 and 3 gear but no light indication on the panel. Someone who has any idea whats wrong? Is this a common problem ? I have exchange the oil, but the problem still exists. Regards Lennart --
Try draining and refilling with plain old 10W-40 from the auto shop. Make sure it does not say "energy conserving" on the bottle. A lot of wet clutch problems like this that people have reported on various bikes have been solved by switching to a different oil. Ted
