it's been rebuilt quite a few times, my girlfriend's dad gave it to me, it's had 3 crank bearings go out on the same side, he gave me a box of old parts that had 6 old pistons in it, so it's definitely had it's share of beating on. also, there's a crack in the back right side of the lower half of the case, that's been welded, i'll have to get pictures up, i hope that won't cause problems
