Funny how all the 400 dyno charts I've seen have a flat top end. My old race 300 gained right up to the redline. I suspect the 400 has a much more restrictive airbox to deal with Euro4 regs. And those racing supersport rules are stuck with it. The bike is choking. Damn the bike could really see gains with pod filters.

My buddy who bought my old 300 is now building a 400. I hope he's not disappointed with the dyno results.
