I just put a new engine in my 99 r1 and when i rev the engine the mph reading goes up when i rev it. also the tach jumps up every couple seconds and then jumps back down. i dont know what is going on. anybody know how to fix the problem?

check your battery connection to make sure its tight.

if it is bouncing a lot, it could be a trouble code, one is for the reserve fuel sensor and the other has to do with the exup valve. otherwise goto the r1 forum website.
