I raced my turbo bike since 2008 throwing the clutch by hand. It was not until my clutch basket failed that it became a handful. Ultimately, I always wanted to go to a multi-stage because, as it was previously mentioned by Powerhouse, it really is the way to go if you want to leave the line consistently. Throwing the clutch by hand on a bike with high horsepower is an art and very tough to repeat.
Hell, read the article I just wrote about my crash. That was from not regulating a manual clutch properly on a bike I had never ridden before. It had less HP then my bike and I was complacent.
Riding it without a lock-up is not a lost cause by any means, but I can tell you, after using the Hays set-up I have now I would never go back. I did my time trying to tame the beast by hand, now I just want to ride and be consistent.
