I just recently had my chain and sprockets changed and now when I am in top gear it seems to make a whining/buzzing sound. Power seems to be a bit lacking at the top end, like the bike is holding back. It seems to get higher pitch the higher the revs. I can almost feel a bit of vibration as well (pretty minor).
I'm worried it may have to do with the front sprocket. It was all done in the shop, not by myself. I do know that my oil needs to be changed and the air filter could probably use a clean / replace, but it seems too much of a co-incidence this happened right after the chain + sprocket change.
Anyone ever had any problems like this before?
