Dear Ralph:
I have a 2006 Crossfire 700 with 2500 miles on it and my question relates to the engagement of the clutch when I hammer on the throttle.  There is a slight clunking noise that does not sound normal.  I have heard from some others that this can be traced back to a Spider gear in the secondary clutch.  Have you heard of this happening to any other owners of the CF700?

There could be some noises coming from the Diamond Drive unit, but there isn’t a spider gear in the secondary clutch. More common is the “clunk” from the rollers in the slotted helix in the secondary. This is very noticeable in sleds with push-button reverse, mechanical or electronic. The rollers have to travel from the one side of the helix slot to the other, and when they contact the other side of the slot you get a good “clunk”. This is why the rollers deform and get flat spots, and is why you might want to consider upgrading to a set of rollers from Hi-Torque. Their rollers are super tough and can better endure the slamming against the helix, staying round longer and maintaining their dimensions far better. Visit www.hitorquerollers.com to check them out.
