MDS ramps thumbs UP

The MDS's are working great, much more responsive then the 10 series.
Have been playing around with gearing, springs , and helix's and have made significant gains....the adjustability of the MDS is nice.
Clutch temps stock were very hot and was able to junk a belt rather easily....now the clutches are barely warm after many long pulls!
HUGE improvement from stock!

Second that. The Rooster Built Pro is dialed!! Could not believe how well it is running. Amazing what just being properly clutched and geared can do for a sled.....
 
Gearing

what gearing are you running?
I need to add weight after the head install and those MDS sound like the ticket.
Stock Gearing, havn't seen a need to change for where I ride. If your running a PA head(13.1) I would recommend having Steve set you up at 66.8, if you have cut your track then 67.3, this combo is ripping for me in the 4-7K range in the deepest of snow, have 0 complaints. Ephrata Farmer and I have the 67.3 and two other buds have the 66.8, the added weight was a plus after cutting my track to compensate for increased rpm and less engine load.

As far as gearing goes did you try dropping the top gear to a 19 tooth, and if so were the results worth it? Thanks
 
I received my weights today and not sure if I am missing some parts or not.. The kit has everything on the list but not sure what the weight plate is(low alt), I think I'm missing it. Does anyone know? Thanks

I have the weight up to 67.4 grams and still pulling between 8000 and 8100 RPM at 6000' in 2 to 3 ft of pow, at Hearts Pass. The MDS's are impressive!! I'm also running the 048 cat belt, works great. I might try 19/42 gearing.
 
800extreme yes BB's 64 grams. I rode at 9000 feet in the Trinities of Idaho yesterday with my setup. 8050 on a loaded pull in weird crust top sugar underneath snow. You would sink down about to your knee or mid thigh when breaking through. Same on the groomed trail. This is defying conventional clutching wisdom. I've never had a sled be so consistently dialed at so many alts and varying snow conditions. I was absolutely certain 64 grams which is my dead on dial in for McCall 6000-8000 would be under clutched at 9000ft 20* and lose snow. NOPE
 
Sorry it wasn't my ride...12 in the group. FYI it's setting up like a death trap up there...somebody is going to bite it if it doesn't bond up in the next set of storms. I have never in my life seen such slide activity in one entire region. There is very minimal snow and it's sliding clear to the rocks on any SE facing gully. There were also a couple of drops in the trees where the depth was not effected by the sun. Those two signs spell disaster for those that can READ. The regular stuff is dumping too but that isn't the scary aspect. That part is a blessing...it's the non normal hills that will get someone this time.
 
???? wrong thread

Wondering what this has to do with MDS ramps???? BB's, riding in Idaho, weird snow, scratching my head here trying to see what point you are trying to make that has anything to do with MDS Thumbs Up.
 
I am running the MDS weigths and have them set up with the following:
Tip=hollow button head and flat washer.
mid=1/4-28 setscrew 1/4" lg.

Mine runs 8,250-8,300 on long pulls and sure feels strong out of the hole all the way to full tilt.

I would like to know what others have loaded the MDS with for weight?

tip hole solid botton bolt and washer, with the tip ground 1/10 of an oz ( just to make sure it dosen't hang up ), total weight of arm 67.4 grams
 
Let's keep this thread up guy's! Give some other people info on the MDS..

Going up with a fresh set of the MDS weights tomorrow, will report.

Thanks Steve for the info!
 
couldn't be happier

I couldn't be happier with my setup. I have had no real competition on the hill except two other sleds almost identical to mine, the PA head, coupled with the MDS weights set up for my area and riding elevation are amazing. This works guys!!!! I am hoping to ride this weekend, stitches out tomorrow hopefully and back after it, two weeks has been too long. See you on the mountain
