Thanks for the additional info. I ended up using a clean cam off of a 1988 Trx200sx. Haven't run it yet, but the part number matched Honda's part number for the 200x. As for the chain, I got a used one off of ebay. When I put it on it had so much slack in it. I just didn't trust it. I ended up buying a DID 25h timing cam chain for a 70's honda and it was 104 links long. I bought a 25h chain breaker and rivet tool to break the cam chain and then re-rivet it back together. It came out perfect. I now have a chain that has 1/4 the slack of the used one I bought and it is a much stronger chain (the stock chain was a 25 chain and this cam chain was a 25h, the h is a heavier duty chain). The best part is it was long enough to make 2 chains, so now I have a spare.
