I had talked with a friend about making some of those recently. I am getting ready to do some engine covers for a different bike with a built in frame slider. I will put it on the list, maybe a all in one pitbull stand holding frame slide axle block.
Yes I agree as well heavy duty chain adjusters and custom axle blocks would be nice! Basically if I had the cnc mill I would try to make all the cool goodies they have for the liter bikes but don't make for the busa. Maybe a nice set of quality clip ons that won't smack into the inner dash panels when you attempt to turn or a keyless fuel cap that's designed better than the crummy 1 from vortex. Custom set of levers or lightweight racing rear sets that stand out from the same 1 or 2 brands you see everybody else use
How about a nice set of passenger peg hangers? There are some light weight billet ones for other makes/models but not for the busa. You could also knock the mount for the left side muffler off of there for further weight savings. Hint Hint
Shorter rear brake levers. I hate having to move from the ball of my foot to get to the brake lever. In fact I need one, so............... How long and how much? Maybe just something that is adjustable.
