RPM Reduction Please help
Out Yesterday Riding in alot of chop for many miles on return only 7800/7900 rpm before running 8150 with Jerry's washers and a Rotax SC wheel . Checked the clutch slip when hot with the SC in place by means for the nut on the wheel 4 nm so very low .
Removed SC checked when cold 8nm , no signs of wear all measure up to spec even 5 washers are ok so re shimed back to 12/13 nm cold .
Have done 15 hours since fitting metal clutch washers ? Have SS wear ring and all looks fine .
Has this happend before to anybody . or is there more to look for, Does it sound like just the clutch ?
Thanks

My 04 does the same thing. When I first take off I can turn 8000 no prob but after I ride for a while I can usually only get 7900 to 7950. I guessed it was some heat soak and I live in St Louis so it is usually fairly humid. I have checked my slip and I think I am at about 7nm so I guess I may need to shime and possibly replace the spring washers?

I'm down ln the 7900 range also, but it's 95 degrees and humid. It's pissing me off. I'm scared to race anyone.
