anyone running the team secondary in alaska or at 2-6k elevation? i just got my team secondary in the mail and mds adjustable weights.

wondering where a good baseline should be? the MDS weights on the scale and weight 80.2 each.

that seems high to me but i know the profile is different, and everyone i have read that runs mds weights suprises me how high of grams there running.

The clutch is a Team Tied with the 71-55.46/71-57.46 helix and red/black spring

what you guys think would be a good baseline for 3-6k?

sleds in the shop getting the rollers replaced on the stock clutch or it would already be on playing numbers!! :)

Not sure with the mds but as a guide I had to drop 2.25 grams from stock with the tied to get my Rpm back where it needs to be. Same helix and spring. I have had much better backshift with the .36 helix though. I do ride higher than you though.

I believe MDS will tell you how many grams over stock you should run, then i would subtract 2.25 from that to compensate for the tied. Should get you close

80.2 will be a good starting point for the mds weights. run ether the polaris black as steve suggests or the cat yellow green for the the primary spring. 71-57 will be good with the red black. run the defection almost even with the sheeves on the secondary and run the 083 belt. I let mine float some like it solid. Hope this helps! You will like it!

Running 80.1 here with polaris black spring. I have been running the 71-55 .46 ramp and red black spring. This setup has been working great for me. I have not run it with the 084 belt yet because I am still on my first 083 belt.
I also have the new .36 helix setting here I am going to try. I also float my clutch as well.

Straight 55 is my pick with MDS weights. Try it with a 200 finish spring.

Also, I see you Alaska guys have room to move LOL. The Tied had less sheave and if you get it right in the clutching you will need to watch the speedo. If your down to the 20 tooth, at 75 mph your belt has started to go below the sheave. At 80 mph you are riding on just the top 1/2 of the belt and any bump will take the sled to the rev limiter. Never blew a belt because of the smooth bottom on the Tied. Nice, cause with the ACT secondary it was and instant explosion. I made a .080" shim to install before the governor (roller thingy) to limit shift 'cause I just can't say no more some times LOL.

Remember the MDS max's the HP to the track if set up right. So 0 to 6000' will never work. Too much HP loss. Set up for the most used elevation. If you set -up for low elevation your primary will overpower the engine up high and you may blame backshift (it's not the secondary).
Let the MDS bring the torque out. Stock engine-pipe spin at 8000 to 8050 max and let it over rev down low.

Tks geo and everyone should get my sled back today then its testing time. i would like to pull 8200 at 3500k.

The temp gun i got should i just do belt temp? Or put a black spot of paint on the clutches and take temps off it?

Spot of black paint, will read better. Make sure to put a spot of paint on both sides of clutch:face-icon-small-ton to keep it balanced. Post your temp #s when you get a chance,THANKS.

80 sounds about right to me

I am running 76.2 grams and Polaris Black/Green (120/340) and most of my riding is 8500-9500 ft. I ran 77 gr and was just a little short on Rs.

I am running the 71/55 .36 helix. Works a bit better then the .46 at my elevation. Pulls the Rs up quicker. I like the black/purple spring.

I see 8350-8400 RPM on the trail down low which is like 6500-7500 ft for me.

I rode some great snow yesterday and was seeing a flash up to 8070-8150 RPM and would build up to 8200-8300 on a long pull. I might try the 57 side next ride.

I also like the 20 tooth top gear.

I have over 600 miles on an 083 belt with zero issues. Love the Tied.

HOW TO FLOAT

How are you getting your secondary to float??... and take it the .36 NEW helix... did they re design one. any info wud be great.

Glenn. If you can get your hands on a 140-200 spring to try with the 55 side, you may like it. IMO, with the MDS weights, the 57 is a good trail helix but doesn't cut it if it gets deep without at least a 240 finish. That is what gives you the higher revs at the higher speeds.

MDS weights are very aggressive and will take a different set-up than stock weights (they don't need a multi-angle to open the secondary). Even the 71 .36 is too big an angle (good thing is we don't stay in that area too long in the spring)). I have ordered the helix I want after trying a straight 57.
IMO the MDS weights in the PC 800 153" will shine in the deep with a straight 55 and the 100-200 spring next season.

You know we are talking about a team clutch right?

If so then you can shim the float plug out to the amount of float you would like, and yes the 71-55-.36 helix is the new one that team made after testing more on the pc 800. We will see how it works next weekend.

Geo-IYO would you stay with a straight 55 and 100-200 for a 162" with a 2.5 or 3" lug? Already have a 20t upper.

Thanks for you insight.

No idea without testing LOL. But I would guess at same helix and the 120-220 spring unless you geared down a bit more than 20 top and 49 bottom (that would be my direction).

I tried the Red/Black (140/240) first. I like the backshift of the Black/Purple(160/240) a lot better.

Did the backshift suffer a lot with the soft secondary spring?

I found the opposite Glenn LOL. I found the 160-240 revier (slowing upshift?) but as for full throttle rpm swings, the 160-240 was less consistant for me ( you know what they say about clutching and opinions LOL).

With the straight 57 , I tried 160- 240, 140-240, 120-220, 100-200, 140-200. Most consistant rpm was with 140-240 and 120-220. 120-220 seemed to be my pick there for mph held but no noticable difference in backshift or rpm.

With the multi angle that I have, 71 .38 (shim added) 55, I really like the 140-200 for straight pull but the rpm are inconsistant in the 71 part (sometimes good sometimes at little low). As short a duration as it is, it is very noticeable in the trees to me. In the 55 part it is acceptable.
When I use the 100- 200 spring in the same helix the rpm is always low in the 71 part but consistantly LOL.

Basically, at full throttle the helix is it all and at part throttle the spring is what I feel and I always seem to get more consistant rpm using the 100lb difference spring series.

I know one thing for sure though. I hate multi-angle helix's with the MDS weghts. Always a comprimise someplace for what I want in part throttle and full throttle feel from 0 to 80 mph.

I think over the summer I will try to make the Tied a tortional clutch LOL. Will that give me a Paragon? Love to play with my clutches LOL.
