TG is 20 min from my house - I stopped going when they dropped golden nugget.

This mornings entertainment brought to us mostly by

The other thing I am curious about is plastic composites can change when the resin is compounded - too much fiber or too little can make a huge difference in the strength of the material - all is takes is a bean counter to fuck it all up.

Yes you can have no deviation on the chassis from oem in pro stock except for gusseting. Had an issue 3 years ago with skidoo teams removing the steering post support that was plastic and putting in a skidoo optional billet one you could order from the race dept. - ISR said the change was illegal because you were removing a oem component to put a new one on so it didnt constitute as gusseting. Clutching/shocks are open same with gearing. Ive seen the cat aluminum ones break due to voids in the casting. usually in the mtn segment things don't typically break like they do in the flat lands due to terrain conditions (3+ ft of powder vs 8 inches of snow with rocks under it)

In pro stock you cannot remove a part that was put on from the factory to a aftermarket solution - you can gusset it but you cannot remove it. Pro open would be the only class you can do it with - the cast aluminum ones break just as easily - you would want to run a fabricated board like B&M.

Heres some Tea for the xc crowd .. Apparently the XC racer from Polaris is not orderable from a dealer, the dealers cannot have them on the showroom floor because they are not EPA compliant like the similar models from Cat/Skidoo . How long before ISR steps in and slaps the hands since all of them have to be Factory production dealer order able epa complaint sleds...

I also find this interesting ... herf is running the SSI belt drive on his mod (not legal on the stocker)

I think you're thinking this is brand specific - its not and I don't claim that at all. I know for a fact every Polaris snocross race sled gets extra frame gussets done if its not rox its a gusset/brace similar to what bender created, Changes are made the skidoo a arms as well as emod/smods. The reason these things don't make it to production is some penny pincher is wondering how they can save a buck here or there. In the instance of the Catalyst/cat - the reason the plating is left out is expense , the reason the shafts are made from aluminum rather than steel - the expense of post processing of the parts (chrome/nickel plating or even black oxide treatment) and pennies saved are dollars earned in production. My bearings in my catalyst driveline were failing after 400 miles , the cat bearings are 24.26 per country cat and are peer brand from china , I am replacing them with SKF bearings (far higher quality) and they are 87.00 each. The reason they use shitty bearings is 100% cost driven. They did the same thing with the old Wildcat X long before textron came in - they had a peer rear wheel bearing for the knuckle that was notorious to fail but they originally had sourced them with KOYO brand bearings from Japan when they car first came out. Engineering was aware of this as factory racers were given the good bearings. In 2022 I had a rxc and right before the I500 there was a bulletin that went out to all racers to replace the upper steering post union with the snocross sled part (rxc was plastic , snocross was cast metal) and then replace the rear wheels in the skid with a heavy duty 4 wheel kit. These issues were know without a doubt (hense the bulletin that went out to all racers) but for production its not a reality due to cost constraints for cheaper wheels and a cheaper steering post union. Again this isn't just a cat thing - its the reality of the power-sports world and trying to increase profit margins or just generally stay afloat and in the black.

I mean considering every racer I've ever met tears the sled completely down and goes from the ground up (not to mention gets the updates from mike on how to make it better than production) and seals the chassis up , replaces bearings etc. That would be why they dont see the failures that the trail riders see.

Impossible... the catalyst is perfect in every shape and form... I've never had anything crap out in this manner in this few miles.

I didn't mean to quote you sorry - admittingly the numbers (jackshaft length, clutch sheave dia) were not factual numbers I used round numbers for the sake of comparison and discussion however the angles and everything from the actual cad of the chain case where the rotation was set.

but theres no misalginment or side loading of the secondary clutch that would cause that according to the internet...

Matthew is a smart guy , he was one of the main mechanics for the former woodies team and does some vintage racing of his own. This will be a positive thing for those still wanting the Fett stuff to have someone knowledgeable continuing on with the brand.

cattleass pooplaris who gives a shit... I'm trying to get sleds sold so I can pickup another...

already been done before... https://www.youtube.com/watch?v=jiUhhDeIvFA
