You know, we mountain twisty and track riders need to realize that there is more than one path to take when modifying their Busas. I used to say things like, "why would you do that?" The fact is, extended Busas look good, some areas of our country don't have the mountain environment, some people like to "do the stretch cruise" in urban environments, on and on....it's all good! I have a 0-6" arm for drag racing, comfy touring and LSR. It pretty much stays at 0" extended but so what? Whatever one likes!
The one thing I would say is GENERALLY SPEAKING, an extended arm (or welded in extensions) in engineering terms...is much perferred over bolt ons. The farther out the arm extends, the more you are asking of the end pieces AND the chain.
