my clutch plate lost some small bits of metal, which in turn got into the primary gear drive and then spat back out by the clutch. we have all the metal out, but ... a couple of teeth, only the ones in the pics, got a little scraped up. would you just replace it off the bat (as I am inclined to do) or run it for awhile and then replace it? have not started the bike since this happened and it only makes noise when you push it backwards.
