hi, is this bike of yours an MC16? in that case, would you be so kind to inform me the part number and manufacturer of the bearings you bought? i'm from argentina, buying a new crank here is more than impossible or nearly equal to the price i've paid my MC16. i've assembled the engine with generic C3 bearings but a few minutes running were enough to kill the clutch side bearing. i've got the bearings machined to reach the required size, of course (one millimeter per side was enough). thanks in advance.
