What are you running for a clutch set up. It looks like by you sig that you have changed the primary weights but what about your helix and springs?

I've got a buddy with a 900 and the stock clutch set up is not very good. Looking for a starting point for some tuning.

Any help is apprciated.

Have you checked snowest? I know you frequent that site...or at least I think I've seen some of the same pics from both sites on here from you. I did a search on there today trying to research the 1M, a dealer here has one left for 7 grand flat......thinkin real hard about gettin it!! Anyway during my search I found 2 pages of topics on the 1M by typing " 900 1m", I'm sure you could find what your looking for there.

There have been lengthy discussions on setup! Lots of folks are messing with springs and helix. A few that I've come to trust have tried some different combos but come back to stock. Many long-time mountain riders are commenting that this is one of the best stock clutch setups to come out in a long time.

Stock weights were 67g, but I was reving way too high with these. I upped it to 70.3g, with stock helix, pipe, and springs. Secondary spring is in whatever hole it came in from the factory. Shifting seems good to me, but then I'm no tuning specialist...I'm sure it can be improved.

I'm pulling about 7600 revs on the flat with about 3 inches of powder. I haven't gotten a good reading yet on a long, steep, and deep pull...either too busy hanging on and watching where I'm going or can't see the gauge for the powder (what a wonderful feeling that is! [:D]) All reports say shoot for 7200-7400 revs max with stock pipe. I figure my tach is probably a little high anyway, and I'm anticipating the loss of 300 revs in the deep stuff...sooooo...I think I'm close. If I lose more than that, I'll take a little off these weights.

I can tell you that I have yet to run out of power! These things ROCK...from 1/8 to WFO, it's all pull!

I was just wondering what you had done.
Went riding with a group a week and a half ago and my buddies 900 worked good stock, but didn't have anything on another guys 800 polaris, the clutching on the polaris was spot on. The 900 has more power but it didn't respond as quick as the polaris with a good clutch set-up. That from the mouth of the 900 owner who rode the 800 polaris. That is why he is looking for a better set up.

It was a Vertical Edge 151
It was a nice sled, even though I personally have never been a polaris fan.
He did mention that the local dealer had set up a number of the VE for the mountains and was very knowledgable about what clutch parts it needed for the conditions here.

Another thing to keep in mind with new sleds is that they dont start making their power immediately. Point being. I raced a 800 VE on a drag strip with my brand new 800MC, i got spanked. Went for a couple days of really hard riding in deep snow running some high temps getting everything broke in. Raced again and pulled right with him up to speed. Bad snow conditions on the strip so it wasnt a true drag but it was clear my machine took a while for the rings to seat and everything to get the new worn off and start working. SO, if it was a brand new sled that was getting worked over by VE's it could just be a matter of time before his machine starts making power in all the right places.

The 900 was pretty new but did have 200+ miles on it so the rings should be seated by know. The owner is pretty clutch savy but was just wondering if someone had a good baseline starting point.
