What are you running for clutching on your new 13 pro?

Well got to ten hours on my pro, love this sled but it still needs a little tuning.
We rode revy all weekend and when I was climbing my sled was pushing 8350-8400 RPM witch is to high for the power curve, everything is stock still, should I just go to heavier weights (64 or higher ) or should I change springs and weights.

Call Steve at MDS and get his weights. They are a night and day difference from the stock weight profile. Way more responsive and snappier in the mid range as well as better back shifting. He also recommends a Polaris black primary Spring with his weights and the black purple secondary Spring.

Thanks I'll give him a call, how do you like your 3" track what are you getting for track speed when climbing?

I'm running 10-66 weights with stock spring MBRP Can and on 91 fuel setting and was at 7900. Was in Mcbride all weekend and worked super all weekend. I would change to ethanol for riding down on trails cause I got as high as 8300 coming back down the trail. Its a 163 stock except can.

I was wondering this as well, just from riding it at home it seems like i could add some weight as well, hitting 8400 at 3000' with 163 track and stock weights (10-62 i believe) usually if i am at 8250 at home it is dialed in in the mountains. I am thinking with all the weight being taken out of the driveline these 2013's could easily handle 10-64's in the hills. Anyone else have any input? pls include track length.

Mine seems spot on for the mountains. 8400 flash in the trails when you punch it, but 8050 climbing in the pow. Couldn't really adjust either way.

Absolutely love the 3" track. I see between 42-44 mph climbing.

Is that corrected for the 7 th drivers?

That sounds really good for a 3" track.

Yeah, that's corrected. I was seeing 47 - 49 mph during a long climb on the speedo, and the drivers make that reading about 8-9% high. That was in about 3' of fresh snow.
