If you look way back on HCS there has been a ton of threads on the STM primary’s for the 998s and most not favorable.
I personally dIdnt feel any support from STM and thought they would at least throw me a bone.
On the other hand I had a issue with my primary from Pro4 we’re it wouldn’t release all the way and mark (the owner) gave me his Fedex shipping # and had me ship it to him and he turned it around that very same day. That in my option that is customer service.
I also hear good things about Tapp but don’t have any experience with them. I did like the fact that pro4 is state side and parts would quicker to arrive if I ever needed any.

Engine rpm shouldn't matter. The primary would be turning at approximately 9000 rpm. The secondary clutch shouldn't be affected by the higher rpms the engine turns. Or am i thinking about this wrong? Ive run traditional cat clutches at 9200 for years on a modded 440 sno pro for years and never had any clutch failures. Although i realize the power difference between that and a 4 stroke turbo are huge. I wonder if its the torque thats the problem instead of the rpm?

Post 5 says secondary bushing came out. He says the primary had the updated movable sheeve. But the bushing came out on the secondary. That should have nothing to do with engine rpm.

Correct the rpm issue only comes in on the 3 cylinder 998 primary and not the secondary’s.
I had no problems with my cat clutch with the movable sheve on the 2 cylinder Suzuki engine.

4,000 miles on mine. Set up for trail riding by Priceless Performance. 42 degrees straight helix with green spring on mine feels amazing. I’m 250lbs running Powertrail CAI and Sandale Hyperflow with 21/41 gears.
