I run an STM old school secondary with a custom 43/32 helix with a green spring, 2nd hole. TAPP runs best with +1 rollers, so your TAPP tuning options work. If you get the +2's as they recommend you'll be full empty and at clicker 6 with no tuning range. I love this clutch, now have over 3,000 miles on 2 sleds. Run between 270 and 300 HP. I like the XS belts best.
Pro 4 is a Far better quality clutch over the stm. The last stm I had took out the center bushing and stm said thanks but we don’t stand behind it.
Call pro 4 and talk to mark himself.
I now run pro 4 primary n secondary’s and belt temps dropped a ton compared to stockers.
I know very little about the tapp clutches other than they have been doing well but for me I wanted to keep my $ state side.
Has anyone had troubles with fuel pump or pressure regulator on the 2013's 1100 turbos? Mine will sometimes struggle to rev up past 2k rpms and get the track going. It just sputters and pops. Starts up beautiful as always. This is not always... I will check my coils. Brand new gapped plugs...
Let me start by saying I have searched this forum and many others like it looking for answers. I have a 17 9000 Ltd with qs3r shocks all around. It has a 129 track With 180 1.50 studs. Cat skis with 6 inches of shaper carbide. I have a hurricane stock muffler bundle with 225,240 and 270...
We are now getting our first stock in from pro 4 performance. The quality on these is amazing.
They use old school cat helix and spring. We will have them for 1100, 998 cat and 998 yammie/nytro.
Combine one with the TAPP primary for a great clutching combo.

How many guys out there have experienced track shaft spinning inside the brake-side bearing on '17 & newer TCats, ZR9000, 998 turbo ProCross chassis?
Over on the TY forum it seems like most Sidewinders have this problem. Lots of warranty going on, and allot have no warranty. The fix is new...
