So.. my engine is opened up and ready for a new top end. I have the kit, and what I thought was a new cam chain and rear cam chain guide, given to me by a friend. Turns out that they're both used upon closer inspection.. he got them mixed up. Grrrr. Anyways.. my chain has much less side to side play and doesn't seem to move as much as the other when you push/pull on the links in a linear motion. Both of the guides have fairly little wear, just a real shallow groove where the chain rubs, but they both look pretty new. Question is this: Should I wait and order a new chain guide(s) and chain or do you think this has some time left on it? I got the bike used, so I dont know how many hours are on it, but there's little wear on just about everything. Except for some carbon on top of the piston, it looked pretty new too. I know everyone says you gotta throw a new chain in when you do the piston, but I dont want to wait a week or two for parts and have my engine opened up for that long. If I could get by and throw a new chain in later next year, that would be good.
