Looks great. Stock gearing with the beltdrive?

So just put on 250km with the Oem primary and viper secondary. Zero complaints with the secondary setup but was running a bit too much weight in the primary as I was about 8200 in the deep wet heavy snow. However, the primary roller bushings that were brand new are beyond the service limit...

I should probably set up the clutch offset based on the viper specs as well I’m assuming. The viper measurement is taken from the back of primary to the back of secondary, where the sidewinder is measured from the back of primary to front of secondary. Anybody have any insight on this?

I have a new 8DN set up right now so will try it just to see. I have got quite a few miles on some of the 8JP belts and have quite a few good spares so more than likely will use them also. I’ve always liked running OEM.

Just put a secondary from a Nytro on my 18 sidewinder. I have a 47* straight helix, epi purple set at 1-0 and 2mm of end play in my setup. Is this a good starting point or is it out to lunch? I am running the Hurricane 270 tune. Thanks, been battling this thing since new so trying this clutch is...

That’s my concern as both my clutches touch the side panel often.

Has anybody added extra vents in the side panels of their SW? I am putting in some specifically on the clutch side to try and rid some heat, and am using a mix of some random Doo and Polaris vents that appear to fit where I want. Panel strength is a concern as the Sled ends up on its side...

So he posted saying he wanted to save money. Then after someone who isnt brain dead did the math, he made fun of the guy, and said it was actually about quality of oil…… lol. Less pink drink is right.

I would look at the bracket that the steering post pivots on down in the bulkhead. Broke 2 on my Sidewinder and its the same chassis. I think Cat makes an upgrade that doubles up all the material down there.

Some adult language, but this is pretty funny. https://www.captiongenerator.com/2151147/Sidewinder-clutch

May try them also. I’m selling the Sidewinder after this season though, tired of dealing with it.

I was skeptical, but have seen guys out east having success so figured I’d try it.

Put my Sidewinder primary back on with a fresh set of rollers that I machined oilite bushings into to give this a try. After 150kms the bushings ID increased 0.015” and they are now sitting at what I would consider max allowable tolerance. They did wear evenly and never egg shaped but I guess...

Well I found the sliders in my clutch (parts 10,11) were installed backwards. That may have had something to do with it. Guess I should have broke the clutch down and checked everything over myself.

Recently swapped over my Sidewinder to a primary off of an Rx-1 / Apex (not sure exactly). Put 500km on with zero wear on the roller bushings and everything was looking great. Went out yesterday and approx 85km in went to pull out a gram of weight and noticed the spider had lost all the...

Put on 130km yesterday with a fresh set of primary rollers with the duralon bushings (as recommended by Yamaha). Mechanics went through my primary again prior and found no problems yet again. I.D of the bushing went from 8.99mm to 9.07 in 2 rollers and to 9.2mm in one. All roller pins measure...

If this round ends up failing, I will defiantly take it to you. My dealer called me today and said Yamaha says to run the rollers with the duralon bushings, they hold up better than the stock ones. The primary spring breaking may have just been chit luck. The primary has no wear on it and the...

I’ve used Lunds setup, and yes it works well. Still trash roller bushings and break Yamaha springs. Have been using the Dalton stuff simply for ease of availability. Truly appreciate everyone’s feedback.

Are there additional shims besides the thick black ones on each side of the roller? Also what twist would you recommend to try in the secondary with stock spring & helix? I seem to be getting good clutch temps at 6-2.

Dalton QAY weights, Dalton black/bronze primary spring (have had 3 OEM primary springs break on me). Stock secondary helix 35*, stock spring. Always run at or as close to 8800rpm as possible.
