Hi all,
I have an MC21 and just got a new 520 chain as the old one was looser than a (insert maternal reference here).
Anyway the new chain is all good and tight which is good - however I have a new problem where because the chain is tight, the inside of it is rubbing against a bit of chassis near the front sprocket. Quite loud when coming off throttle. If the chain was a tiny bit more slack then it would not touch. However there is no more give in the rear wheel position to loosen it.
Anyone else ever have the problem? I'm thinking of just waiting for the chain to stretch. However its not a nice sound when you are trying to sell the bike!
