Powder blue got me thinking on Yamaha's reasoning for having a floating secondary on the jackshaft and a point I would like to make would be parallelism with the primary clutch. While the primary is said not to move from the factory the tolerances for the clutch allignment is +or- 1.5 mm now when you look at that tolerance with a fixed engine (no real easy way to move the engine) look at at the back of secondary this tolerance could be as much as 5 mm. I know it is rare to see a clutch this far off but to the guy who wants premium power to the ground and good belt life this wouls make a world of difference. Getting back to he floating shaft most sleds excluding the rx1 have a reasonable way to accieve precise parallelism thus more efficiancy. Now to help you all get a better understanding of what I'm trying to say if we could move our engines like on a two stoke so we can make the primary perfectly parallel no tolerance, then I would agree on a fixed secondary. But with no realistic way short of removing the engine and modifying the mounting system to achieve precise parallelism then I would have to think a floating shaft would may be your best chance at efficiancy. Just an opinion of a clutching finatic :idea: :?: :idea:

A floating shaft won't affect whether the clutches are parallel.
