I've got a TMS250 (re-branded Lifan LF250), with which I am generally delighted; however, I have noticed something odd: the front and rear wheels do not track in the same groove when the bike is traveling in a straight line.

1. Given the possible spatial misalignments that could cause such an occurrence (there are MANY), what is the best way for me to determine which misalignment (or combination of misalignments) is responsible for the "problem" with my bike?

2. Have you (or one or more others you know) else encountered this "problem"?

3. If so, how did (you/he/she/they) go about trying to obtain a perfect alignment?

4. What sort of results did these efforts produce?

5. What, if anything, would (you/he/she/they) do differently if you were to attempt such a project in the future?

THANKS!
