I wouldn't do it (but then I am not planning on picking up one of these beauties for a long time) but has anyone touched on the idea of removing the balance shafts for less weight and parasitic drag (a FOR RACING ONLY mod, I would suspect.) I know in the import drag racing world they do this, but I also know it is detrimental to the life of the engine. |

The Superbike Aprilias ran without balance shafts when Corser was racing them, and seemed reliable, but vibed a fair bit. Then again, these engines did 300 km before being changed or overhauled.... |

I'd suggest keeping the balancing shaft.......just skip breakfast if your that worried about the additional weight. Syar |

I'd suggest keeping the balancing shaft....... There are actually 3 of them, but dieting is probably an easier fix. |

Not if you're trying to reduce rotating mass. |

I'm sure that when these bikes are built into track bikes the tuners will remove the balance shafts. I do NOT recommend doing so on a street bike. The service life of a race engine is measured in hours or minutes, where the service life of a street motor has to be measured in years or thousands of miles before tear down and re-build, and comfort matters. The goals are 180 degrees out of synch. |

And apparently the reduced vibrations from the engine allowed the frame to be constructed differently. It may not even be a good idea for an endurance race. |
