Installing a timing advancer is project #76 in the 101 Sportbike projects book. For the ZX-6R, it was easy, so you could probably do it yourself. But for an SV650 or busa, it requires flywheel removal. At the higher elevation, the timing advancer should work great. Will improve throttle response, but may not change hp. At sea level, you have to be careful about detonation.
If you don't have the Power Commander, the book (project #73) says it "is about the easiest bolt-on (or is it plug-in?) process possible."
