  1. The nut was tight. This scooter has been ridden hard but the internals have never been molested. I'm second owner but I know the orignal purchaser (old riding buddy) so I have history on it. I have seen the inside of other XR350's engines that have the same issue, so I suspect that it's some kind of an XR thing that occurs with age / use but am having a hard time figuring out what's causing it. It almost as if the transmission shaft bearing is working its way out of the case, causing the clutch to rub on the cover. Tom
  2. Thanx for the reply! The bolts haven't backed out. The outer cover is rubbing on its face, the part that faces the cover. There's a even wear ring mark about 1/2" from the edge, all around, so I don't think that the shaft is bent. I'll definitely investingate that situation, though. The rubbing is on the part of the cover where the actuator arm is mounted. Could worn out friction plates cause the outer cover to shift? Thanx, Tom
  3. My son's '84 XR350 is making a wierd noise. It sounds like a rubbing or "whirring" noise coming from the greabox. There's lots of shiny silvery stuff in the oil. I pulled the right side cover and it looks like the clutch "outer" piece is rubbing on the inside of the cover, right where the clutch actuator arm is mounted. I'm not familiar with this type of clutch linkage and am having a hard time figuring this out. Obviously something is worn (this scooter has a lot of fun on it), but what? Clutch plates? The cover's not smashed in as far as I can see. There doesn't seem to be any play in the clutch basket. Has anyone experienced this before?

  5. While you're at it, check the condition of the rod bearings. These XR's were notorious for wearing out the small end of the rod. Tom G
