I dropped my 1992 sportster 1200 on the primary side, it was in gear and running when I dropped it, there's no damage as far as visual damage but now it doesn't want to go when given gas. It revs up but doesn't want to go anywhere, I jacked the tires up off of the ground and when I put it in gear the tire will spin but not very fast even when I get on the throttle. It will shift through all of the gear so I don't think it's a transmission issue but I'm lost as to what else it could be. Any ideas? Could I have damaged the clutch by dropping it while it was in gear some how?
