speedo bounce, normal?

[81xsproject]

My speedo bounces back and forth about a 4-5mph span while riding. Is this bouce normal?

Not normal...probably indicates the cable is binding or giving out. Might try lubing the cable or replacing it. Also look for misrouting or such that could cause too tight a turn in the housing...

If the front wheel has been off, you also want to check that the speedo drive has been put back together correctly.
