you know what dry sump lubrication is right? well, that metal pipe that goes from the gear case to the engine head on my raptor 660, the hollow bolt, its stripped in the inside, not the bolt, but what you put the bolt into. what do i do? can i re-thread it? if i do, those bolts are hard to find. i dont even know if they sell them as a single bolt. i tried to put Teflon tape, but that just slid up to the exit hole on the hollow bolt. its stripped so that the bolt can move freely in and out. any suggestions?
