Hello all, first post in some time here. Somewhat of a unique situation I think. A friend has a 2020 SW XTX. All stock except the Hurricane/Hindle Mountain Lite can. A few days ago the sled blew a belt while under heavy load. The belt disintegrated, and a piece of cord wrapped up in behind the...

Hi all, for the Tcat guys here…can anyone confirm if the belts from 2017-2019 Thundercat/ZR9000’s are interchangeable? The part numbers are different, but I’m not aware of clutching changes between the 17-19 model years….thanks in advance.

Hi all, my 19 Tcat with the Earth X ETZ14C battery went dead on the lake yesterday. It started, but stalled after a few minutes while idling and would not crank. We found the battery to be at 8.8v. Thanks to SideshowBob, we swapped out the battery, but the dash indicated it was only producing...

Hi all, I have the TD Max Spool 17, and added the TD Gen 1 header, with updated header map. I’m running the 3 bar, with 3” exhaust. What boost pressures are you seeing with MS17, with the header? Thanks

Question here for the Cat guys…any opinions on the Tornado secondary conversion? Pros and Cons?

Hi all, Aside from the clutches and cosmetics, are there any real differences between the SRX and Tcat/ZR9000 within the same model year? I have searched, and do not see anything obvious. I have heard the ECM’s are different, but I am not sure how/why. Thanks for your input.

Hello all, any significant updates done to the 21 SRX compared to previous years, aside from the chaincase sightglass being removed?

Does anyone offer a 25 tooth upper gear for a SW? I had a failure between the splines of the top gear and the reverse actuated gear today and am looking at my options. Thanks.

I read here somewhere that the knock sensor can be activated as a result of improper track tension, perhaps caused by the drivers ratcheting while under load, or from the track whipping? Anyone familiar with this? Thanks.

I have a 2009 Apex MTX. Front limiter straps are as long as they can be. Can’t seem to get it to weight transfer very well. Any suggestions? It’s used on flat land... Thanks.

Anyone with experience in using an advanced timing key in an apex? Any hp gains to be seen with 2-4* advance?

What are the common performance upgrades on the 4 stroke Phazers? I have a 2010 with Excel exhaust, otherwise totally stock. It is revving out to 12,300. I'm assuming it's losing HP at that high of RPM but I can't find factory spec....seen somewhere the suggestion was 11,400? Anyone with...

Does anyone know the angle(s) of an 8BV86 helix, or what they came on? Thanks

Hi all, I have an Apex built for snow drags with an MPI s/c, stage 2...2 1/2. Running 18-19psi at 10,400 on pure C14+. PC5 with Autotune, POD300 data logger etc. This was built a few years ago and has dominated the local snow drags. At the end of the season, I began having a few issues with the...

A buddy just bought a new SW. On the first ride, he noticed a loud noise from the primary when he lets off the throttle. The primary cover appears to be slamming against the primary bolt washers(2) when the primary relaxes. The weights do not appear to be touching the rollers when shut off. Is...

Hi folks. I'm looking at a new Raptor 90 for my 6 year old. He has outgrown his Suzuki 50. Anybody have positive or negative comments on the mini Raptor? The Suzuki has been a great bike and I would consider the larger Suzuki 90 as well. Thanks

I just bought a Nytro Turbo. I am at 1400' elevation, running up to 10-12psi of boost. There is no head shim and I believe the pistons to be Stock. I'm sure it's not safe on 91, but do you think it's safe to run with a race fuel/pump gas blend or on pure C12-C14? Thanks for your input.

Hi folks, this is my first post on the TY 4 stroke side...thanks for the great forum! I just bought a 2010 Nytro sight unseen. It has only 800kms (500 miles) on the sled. I had it shipped to me from Alberta. The seller stated that it had an MPI 180 rear mount turbo that produced 5-6psi of...
