Country Cat site shows p/n 440-09105 as superceded to 6639-448. And, Cat calls their own slides Tiger Slides. Cat does still sell Vespel brand. Tiger Slides show priced at $120 per slide! 8639-422

As successful as the 998 Yamaha engine has been, what could Textron possibly come out with to equal or improve it? ZERO. If someone at Cat/Yamaha/Textron thinks the 998 has gone stale, then add some spice (+2 more lbs of stock boost) with virtually zero risk to add some more pep in 'er step...

Have to do some research to find out what kind of plastics are being used but maybe Dorman? They have lots of different push-ins. Other than that, might have to buy Honda, Toyota, etc.

Put it in Catalyst chassis w EPS and increase stock boost 2 lbs. :)

Over the years, I have run/experimented/tortured most of the belt brands out there. Today, there are a few I don't have experience with. Going back to the first days of 998 turbos in 2017, Carlisle (who first produced the brand name Ultimax, and now owned by Timken), sent me and a couple of my...

IMO, if chain rubs on center post, it's too loose. 21-38, 21-41, etc. In general, I think most would want largest top gear available for the ratio they choose to run.

One of the changes I made was to increase ski pressure. I left center shock in rail pretty light. Also wanted to try front shocks dampning up at middle setting instead of lowest setting. Ran out snow so never really had a chance to test my changes. Next year. I now have setup that favors...

For the short season here in Midwest this year I was running semi-agressive SnoTrackers on Cat skis. I decided on semi based on this site saying agressive is too much on Cat skis. Without allot of time to try to dial them in, what I can say is the semis are not aggressive enough. I had my toe...

It's physics - balance/harmonics/resonance. Unlike the "Knockout kit", what you're running actually changes (in a favorable way) the harmonics at play with the primary.

Yes, PS looks better and better as I climb age scale. Keep the faith though. I'm considerably older than you; have had 3 failed rotator cuff repair attempts, and now a complete right shoulder replacement (last year), also 2 attempts at repairing ruptured biceps on both arms, yet I still ride...

To get 1.25 RipII you'd have to order from either Cat or Yamaha. Aftermarket RipII are usually fully clipped and no quiet track.

I have always relieved stud heads wherever they intersect quiet track. Pic shows a 15/16" dia. hole saw with wood as a stop, that has an arbor mounted in it. I use washers to adjust how deep saw cuts. I first drill track, then use this tool wherever needed. To remove the rubber, I just use a...

It's physics - need high cylinder pressure (i.e. Boost) to push rings against cylinder wall to break in rings. Coasting/idling engine doesn't produce high cylinder pressure. That said, I don't run to "heat soak" level before allowing cool down. High cylinder pressure repeatedly for short...

Yup. Run it like you stole it!

Engine is same all years as far as I know. P/n's for rods, pistons, rings, crank, valves, head, block are same.
