Re: XC600 Crank Bearings
Is there a chance you sucked in some snow? On those piston port motors, sometimes if you are in deep powder, you can suck some snow in and clean off the lube on the pto piston causing some problems. The easiest thing to do is take off the carbs and look in your intakes and see if any of your pistons are all scarred up. Then take a bore light and one by one drop the pistons to the bottom of the stroke and look in through your spark plug holes to see if you see any scarring on your cylinder walls.
