My TAPP came with plus 2's, I switched to plus 1's from Thunder in an effort to find RPM's. I also put new bushings in the rollers this year.
I will say I have been fighting to find RPM with this clutch from new. I have had it on 2 different sleds with 3 different tunes. When I first bought it "set up" for my 2017 with a SM tune it was so heavy the knock light would come on hard pulls. I slowly pulled weight until I was left with the lightest bolts, plus 1 rollers and 2 set screws on a PM tune.
I did not use the clutch in my 2022 the first year I had it because I ran stock tune. I knew a stock tune would never pull RPM with that clutch.
I have never had an over rev problem; I would actually welcome it so I could see where the tipping point is.
Maybe I need to switch to standard rollers?
Ramps have always been on "A" When I get back from my trip, maybe I will flip 2 ramps to "B" to see the effect.
The clutch probably has 5-6k miles on it now and I have it completely empty, shortest bolts, plus 1 rollers, black spring on a sm tune running at 240 90% of the time. With a 39- 35 degree helix, B-O spring at 90 deg on stock rollers it is just about right, comes out at @ 8700 and climbs to 9000. Put Hi-Torque rollers in and the RPM's fall 3-400 and I am out of adjustment, except maybe going to an 8JP.
The main reason for buying this clutch in 2018 was durability. I was afraid of the stock clutch on long trips.
I think it is due for a rebuild and I will probably send it in after this year.
