What kinds of problems are you talking about when you say "ruining your bike"?
The only thing negative that I've heard about the turbo is that the clutch slips during full throttle roll-ons, but I haven't talked to enough Rocket III turbo owners to verify such a thing. And I don't even know if those problems were with the Turbo Connections turbo or another turbo setup.
I don't know anything specific. Was the bike desgined for 300 hp? I would think that doubling the torque would take its toll. I'd be more concerned about the engine and transmission life than the clutch. I'd like this bike to last more than a couple of years.
