heres the deal, I got an 85 with shot bearings and my sprocket is toast to. the bad news is the chain tensioner teeth are almost gone. wanted to just buy a billet carrier with new bearings but all i've seen say there for the 86 350x. 1 site said will work if you use an 86 sprocket. now this is the confusing part. i just bought a 86 sprocket off ebay after going to the honda site and it saying there the same sprocket! has anyone done this and what are the differances? my sprocket nuts(on the carrier side) are all hogged up anyway so will have to be replaced. I would love to just replace the bearings but have to find a fix for the chain tensioner. any help would be great . thanks
