If you're not prepared to mess a bit, then don't mess at all!
I know how tempting it is to do a little mod and not spend time setting the bike up - I fitted new pipes and went for a ride. Siezed in two miles...
The question is, would you rather spend an evening messing for a nice power increase, or two weeks and two hudred quid waiting for a barrel replate and new piston?
