Theres a GPX250 for sale fairly cheap which I was thinking of buying, Cosmetically it was perfect, however at idle I noticed something odd. The clutch release shaft (the shaft on the side of the engine the cable attaches to) slides in and out at idle (Not much, only 1 or 2 mm) (up and down (moreso in and out of the cover), it doesn't turn). I was thinking the shaft that the clutch is mounted on was is bent, however I'm not very familiar with the GPX250 engine. Could it just be the retainer for the clutch release shaft? Has anyone had this sort of problem, or can anyone shed some light on it? Could it just be a badly assembled clutch?
