Who makes best Adapt Clutch Cover

[jonlafon1]

I wish Thunder would incorporate their belt adjuster into the cover like the other 911 covers. I have had one on a couple of sleds. Being able to adjust moveable sheeve to belt clearance makes a big difference on how the clutch engages. I believe it also keeps heat down in that low area of the primary.

100% agree Rich on the moveable sheave adjuster. Smooth as butter engagement! Problem is on the catalyst not enough room between clutch cover and side panel for a adjuster. I bought my cover from Precision awhile ago. Like 2023 some point

That is what they explained to me when I contacted them. I want one for my new Riot 9000.

Catalyst is really tight in the clutch area. Belt removal is not easy. Once you do it a few times its okay but its TIGHT in that area on the catlayst. It took me alot of miles to get mine running right. Its flat out rips corner to corner. 600 trail ripper. Really fun sled and the catalyst begs for rider input. it is NOT a sit and ride. It loves when you move around and lean. Totally different sled compared to prcross. IMO the procross is more sit and ride cruiser.

With an updated cover, can the Adapt handle your Stage 4 PEFI Tune?

Could the clutch handle another 5 mile WOT river run??? Lol

So far, pretty good results. My ADAPT, in it's early life, survived over 200 pulls on track dyno. 100 of which were using anti-lag with high boost settings. I only have been able to trail ride about 1500 miles. Clutch and belt temps nicely warm, not hot. Very little belt dust. XS belt.
The only negative issue I've experienced is the factory roller bushings don't last. I've begun experimenting with different materials. TP hasn't had time to work on these yet. It's on their "to-do" list.
I've already found one that's better but I others to test.
Still playing around with setup (primary springs, helix). Using stock secondary spring.

Not apples to apples. But I now have 3k on my catalyst 600 with the adapt. I concur on roller bushings AND the weight wear also. I’ll say in my experience the roller bushings are going to wear and if a when this gets solved which I have with bushings from Dyna Tek then the weights start to notch out/wear grooves. So IMO you either face roller bushings wearing out in 1000 or weights in about the same mileage. This weight wear/roller bushing is especially prevalent on grade trails or when holding throttle position for long periods. It IS happening on a tuned 600 adapt ? What’s it doing on big power? I’m not totally disappointed with the adapt BUT you either get roller bushing wear or weight notching. It’s harmonics IMO. It don’t matter what weights your using they notch on these adapt clutches. This is two stroke side. Just my observations. CAT needs to address this issue. Think of the riders that have no knowledge of clutching or checking clutch components every 1000 miles or so? IMO this is a big fault on the adapt.

I wonder if the 2 stroke vibration is doing the damage.
I have over 2000 miles on my ADAPT with no issues. Spider is still tight.

I just got a torsional set up from a member here and I cant say what kind of performance gain I am getting, if any, but I can tell you that it is noticeably smoother. So much so that on a ride Friday I switched secondaries with another 998T at lunch to see if I was crazy.
I said" I know my impressions, but I am going to wait to tell you until after you ride it on your sled to see if you get the same impression." First thing he commented on was how smooth it was compared to a compression set up. That how much less throttle it seemed to take cruising down trail. He is ordering one today.
I don't know why it is smoother.
Does the torsion keep the rollers on the helix better?

My spider is still nice and tight too. About 1850 miles total. My weights (BDX ProMag weights) and weight bushings are like new. No signs of wear. The 998 must be easier on clutch than 2 strokes. Only my roller bushings wear.
I sure wish Cat would figure out how to design and make a clutch that would hold up and be efficient.
