I am not hitting the rev limiter at all. It does initially pull higher and settle down though.
Well sounds like you just have to much weight. Start taking it out of the tip till you get around 8800 then take some out of heel till you hit 8900.

Well.. Had an interesting day today. Snapped 2 helix studs off the secondary running at 20 mph. Never seen anything like it. Got it to s dealer and got a new used sheave for $75.
Then 10 miles later back on the trail on a WOT run I actually broke a supertip weight in half. Felt s little blip and thought it was the belt. Turned out to be the weight. Managed to get ahold of the same dealer and they gsd a set of goldstar bikeman weights out to us and met us at a bar we had just passed.
Anyone ever seen any of this? Could there be a harmonics or vibration issue?
I did get the rpms up to about 8600-8800. Stomped on a 14 800 doo, but didn't run much else.
By the way Pats Yamaha in Greenland rocks!

Pats is a awesome dealer! I suspect the studs broke and took out the weight when they flung at it? I know on my SRX when the secondary broke those studs the helix or parts hit the primary and ruined it also so look carefully at both clutches for damage. Nothing to mess around with. Could really hurt a guy at rpms these motors turn.
That said I suspect your helix wasnt seated in towers all the way and when tightened studs snapped or on removal of the nuts it wasnt notice the stud was unthreading. I always Loctite those studs into the Helix for that reason.

that's actually a theory I didn't think of that the stud could have hit the weight weakening it.
To double check, when you install your helix, do you get it seated all the way down by hand then tighten the bolts? I usually get it about halfway, then let the bolts seat it as the tighten down. Maybe I've been doing it wrong all these years??!?

I try to. Or at least try to feel that the step goes in easily and tighten nuts evenly little at a time each.
