I would keep it and put a turbo on it. Thats just me. I dont understand why someone would spend thousands of $ to make a busa a twisty bike. If thats what you want should have just bought a 1k or 600 just my opinion. I mean the busa wasnt built for twisties why make it a twisty bike. Nothing wrong with revalving forks and rear shock as they arent designed for us big boys. I just dont understand, but i probably never will as i'm not that worried about taking high speed turns. Good luck with your decision.
