Hello all ,, i am about to buy my 99 Busa only ( 7g ) mileage,, and am concerned with the ally subframe,,, how easy are they to change and can i push a dealer to change this,,,also i have read loads of great info on this very friendly forum,, but am concerned that i may be buying a bike that will need constant work, going by all the trouble shooter posts i have read,, i dont mind getting hands dirty at all but not every day,,or am i just flapping,,,yours truly ,,,BUSA FANATIC..
