I would probably feel the same way but, this tuner/mechanic has a strong reputation here as a engine builder, tuner, all around motorcycle mechanic(specializes in metric bikes), retired stunter, road racer, and basically a good guy that only will promote what he knows to be truth. Not to mention, he is "The One" that all of the local busa guys go to(other than the posers and super squids). I have worked with him in his shop and see him build drag bikes, street sleepers, and full blown blingers. I honestly feel he would not shoot me a line of crap and he knows I turn a lot of my own wrenches. I wouldn't even bother him with an oil change, lol. I am like all you guys & girls, I just want to do what is best for my busa. That is why I switched to full synthetic but, now I am undecided again. Dammit!
