Thanks for the advice...
If I get it I will probably put a new top end in and fix/clean up w/e else needs to.
Then ride it for a little and if I really like it keep it and if not I will sell it for around 800-1000...
But if you bore out the sleeve even more doesn't it make it less reliable...
Isn't that why they stopped making the 260bbk? Because it was so thin it would crack easily...
