Longest Lasting Rollers

[Fleecer]

I'm going to be putting the 16mm clutch rollers on and would like to know how they will affect the shift vs stock rollers ?

Going from 14.5mm rollers to 16mm rollers will raise engagement by 200 rpm and raise shift rpm by approximately 300. Should be able to add 1.5-2 grams more per weight.

Rode yesterday with a fellow that just installed Thunder Products primary rollers and one was shot after just two days and 250 miles of riding. Yikes, He's not to happy with that kind of lifespan on them! He's running Precision tunes on 250 and 280 for the most part.

Have over 1250 miles on the stock 14.5mm rollers now and they still look good running on Hurricane 270R & 290R. Had one bushing move on one roller at about 700 miles, i just pushed it back into place and its still good. So just as I thought, keep the belts from blowing and the rollers will certainly last a lot longer. I always thought that a belt blow was cracking the stock vespel bushings shortening their lifespan. I was only getting about 600 miles from them before when belts were blowing.

I want to try those brass bushings from G-Force, but they don't e-mail me back.

Any updates on which rollers last in the sidewinder primary clutch?
I have run stock rollers,
Stock rollers with replacement older yamaha bushings,
TP 14.8 rollers.
Non of these have lasted for me.
Today I am going to run a set of 15.5mm rollers out of my nytro. I will add clutch weight of needed.

My stock primary rollers are still going strong with 6300 miles on them. All stock clutch components with exception to added tip weight. Yes I run the mild/medium tune, Max Spool 16 3 bar currently. I question the rollers life with aftermarket weights, but whereas others have still had bad luck with same, who knows for sure?

Shall be staying with stock size rollers when time comes. Have ordered the Yamaha replacement bushings for when that time comes. They are the green yellowish bushings that I found on this site with a bit of research. Roller size does affect rpm range and I don’t want to start all over with my clutching set up.

Heat kills those original plastic bushings from what I have observed from others. They seem to almost melt with how they kinda ooze that black plastic bushing material to one side when they fail??

Oh should state that my clutches have been machined by dealer since about 1400 miles, but I don’t see that causing any better or worse bushing wear.

When the black bushing migrates over and the bushing locks up if not caught right away the bushing will then wear out on one side.
The yellow yamaha bushing seem to just fall apart like delamination.

How long do the rollers last with the bushings
@STAIN was running?

I'll go out on a limb here and share what I've experienced on roller wear.

In 7000 miles, I've ruined 2 sets of rollers. Both sets, I was spinning sled 8700-8800 on a long pull. Imo this triple has some sort of vibrant frequency and when held a mile or more at 8800, the weights hammer the rollers. I can ruin a set in a day doing long pulls at that rpm.

Turn it up 9000-9100 sleds topend better and rollers last forever. A lot of tuners want 8700-8800, which i think is fine in 1000ft, but run a mile in the slush at 40f and anything over 9000 will run better. Just my findings....

Even with added weight you may turn a little higher oupt of the hole. You may have to add some helix angle to keep rpm in check when taking off from a dig.

When running big rollers, I go from a 35 helix to a 41/35. The 41 ties it up out of the hole and runs a flatter more consistent rpm across the board. Just my opinion however.....good luck!!

15.5 mm rollers last a long time. I run them on mine. 43-35 helix. Works well. 2600kms on an xs825 this season and still looks great.

Awesome! What secondary spring and what's it set at?

I have a black lime dalton a 0-1. I know a lot of guys are having luck with lighter springs in the secondary, but my clutches are clean and run nice and cool. I run pretty hard too. Lots of wheelies,
Lots of anti lag and high speed running. I never thought a belt could last this long at this power.

The most durable for me were Gforces ! 15mm full width...They use the smaller washer each side of the roller from the old clutch. Some sort of oilite bushing. I also had lots of success whit 15,5 std roller whit CUSTOM torlon xxx bushing

I have thunder products primary and secondary rollers now with approximately 1000 miles. Primary are shot I would not recommend

Would like to know the primary weights and tunes used in your applications please?

This I can say...the heavier the weight and spring combo along with high hpr flashes, the worse it is on our rollers and any roller in the SW clutch. But, it is not the roller's fault, it is the SW clutch. These rollers have been used in Yamaha sleds for years. But the SW comes out and now there's issues with our rollers....wonder why?

I'd tend to agree with this as well. Take out some weight and let em spin up higher.

My friend and I that switched to the old primary clutches also found roller wear to be a non-issue with the old primary, and as an added bonus, better performance and much improved belt life.

Well now I need to remove some tip weight to get rpm's in check. Above 100mph in the mash potatoes trails today my rpm's would drop down to 8300 rpm. It would pull 8700 until above 100 then drop, last weekend I thought it was slipping in the primary so I added some tip weight.
Fast fwd this morning i changed my secondary setup to 41-37 helix with the TP orange wrapped at 3-1. 15.5 mm rollers in primary.
My 1.75 track is blowing the mash potatoes into the next county below 30mph.
Coming off a corner at 60-70 mph I can't steer due to the skis being in the air.
After 200 miles today rollers still look good and spin.
270r tune.
The tuning fun never ends...
