- 22 ZR8000RR, researching for a Tcat/Sidewinder
Long time listener, first time caller. I posted this thread over on HCS and getting a lot of cat answers as expected, figured I get some more from the Yamaha camp.
I'm starting to look for a 998T for this season. In between new leftover models and used, and wanted to see what everyones thoughts are in 25.
If I go with a new leftovers/low mile 23+, where are we at with the ADAPT vs. Yamaha primary? I've seen a lot of older threads, but not many recent ones except for some reports of ADAPTs cracking. Does the billet cover actually fix the issue? As for the yamaha clutches, i dont mind noise, do the updated rollers last a whole season? From what I understand Yam's have a really nice secondary.
I've also been looking at used sleds under the $12k mark. I found good deal on a TD tuned 2019 Ltd iACT with 3,500 miles that seems like it was taken care of. Has a decent list of "bulletproofing" done, upper gear/brass shift pads/BOP repair bearing/tensioner tack welded/belt guard/belly pan protector. TEAM clutch on it, but for the money Id be saving I'd swap in either a TAPP or a billet cover ADAPT. Add a QS3 FTS, and drop in power steering and I'll still be well under the cost of a new leftover.
That said, I dont remember what the Limiteds deal was vs the Tcat in 2019. They both have Fox zeros and an HPG FTS right? Does the tcat just ride lower?
Also, has anyone successfully swapped a 2019 iACT module and cluster for a 2020+ version to get the separate front/rear suspension split?
Finally, aside from the usual used Procross things, anything specific on a 998 approaching the 4,000-mile mark I should be checking out?
Thanks

Get EPS. You won't go back after riding an EPS 998. Thank me later.
some issue get blown out of proportion but I would at least address the following right away.
Drive shaft, either the saver or the bearing.
ROV and crank case vent to air box. Get that crankcase vent rerouted, oil in the airbox can soak your air filter and drip on the primary.
I would address the upper gear bushing at first chain case service, along with tacking the roller bolts.
If you have a CAT, maybe install a better cover on the ADAPT. The TEAM primary benefits from a 911 cover, making the sheeve to belt distance adjustable which I believe helps with the cracking some experience in those primaries.
Yamaha primary --keep an eye on the rollers, although the failure rate on the newer ones seemed to be much less than the early ones.
Yamaha secondary--you might want to change the secondary spring as the stock one can coil bind at full shift out.
Ther are other things like cutting down the clamp stops on the throttle bodies if you tune it, charge tubes etc. but these things can be done as you go.
Very addicting power and a good riding/handling package for sure.
