figure bringing this back to the top might help out those with new sleds this year........................
question for those who clutched their D-8's
- Thread starter AKSNOWRIDER
- Start date
yes I put one on top and 2 on the bottom....
Clutching
AK, Thanks for the great post, I am still a little confused as to what set up to use for my elevations, what do you think would be the best set up for a 09 D8 163 with stock pipe and hps can, and a single slp set up ? as I have both. I run from 2 to 6000 ft, mostly around 4500 to 5500 ft. I am picking the sled up today with all the new up date's, do you think their will be anything we will have to do different because of the updates ?

what I run right now endo is the 62/42/.46 helix, 3 delrins, stock 160/240 secondary spring , slp green/pink primary(160/340) with 68 gram mtx weights with 1 gram in the tip and 2 in the middle..this pulls 8300 rpm at 4000-6000ft. with the slp single on my 163..if you need more rpms pull another gram or two out of it....from 200-400 it will pull right at 8400-8450(right where I have found it to pull hardest) at lower elevations I have to add a gram or two to get it under 8500 ..as for the update..we shall see..I am also changing the track and doing fastrax drop and roll so it may also change things a bit..will let everyone know...
I was asked to bring this back to the top again....how is everyones clutching working?
Bringing this back up for some guys on the IQ forum. Mountainhorse, could we get this thread moved over there?
Thanks
Thanks
Ak... when you say 68 gram mtx, is that the base weight? meaning empty or without the rivits. So total it is basically 71ish grams?
yes..68 gram base weight with 2 grams in the tip and 1 gram in the belly of each weight for 71 gram total weight....
Yep...already have it set up and ready to try. Want to try my "proven" clutch set up I have been using to try out the new updated parts first then will slip on the Team Tied secondary to see how it works...do not want to make too many changes at once in order to keep track of things. I am sure other adjustments will need to be made in the whole clutch set up as the bugs get worked out. Hopefully others will be working on it also so we can work out things together. I am starting out with what SLP is recommending as a starting point.
800poodragon how did you determine what helix to run in the team tied. I really want to run the clutch but do not want to spend a fortune buying helixes to figure it out. I know they say it should pull about 14 degrees more angle but dont want to go primarily off of that. I wonder if carls cycle has a setup for them yet, surly they had a tied secondary and testing it last year. I talked to slp at the puyallup snow show and he said they had been testing last winter with it and that they had a setup but would not say what it was.
would 19/43 as gearing work? not to much doglegg?
several guys on here have been running it and said they like it..I would assume it would be fine...
I think the chain length will only allow 19/42 won't it? That has worked really good for me.
I want to get some of you thinking a little bit here. Why are we running team secondary springs with such low finish rate? OK, well I'm not.
I was playing around with the team helix/ spring spreadsheet thingy. So I did a lot of variable changes with helix and springs.
Knowing the secondary has the most grip at engagement due to sheave angle and belt contact. It also has the least side pressure at full shift out. This could indicate an increase risk of slippage. Especially with the stock 160/240 spring.
The primary has the least pressure at engagement and the most at full shift out. This is again due to the angle of the sheave faces. We counter this with weights and helix, etc.
So from a belt side pressure stand point these are somewhat opposite each other. When the primary has the most pull, the secondary has the least grip and vise versa.
So, to create a scenario, If you are climbing and the track is getting good traction it is working against the secondary (torque converter) If the primary is still pulling hard it is going to over power what the track is doing and slip the belt. You loose track speed and then get stuck or something.
So, if I take the stock helix of 56/42-.36 it takes a 160/300 spring to equal the same side pressure at full shift as it has at engagement. With an obvious peak when the angles change.
I was using a 160/280 spring with the 58/42-.46 last season with really good results. I'm starting to see why.
Play around with the team calculator a little bit and let me know what you are all thinking.

Had the shop do a clutch kit following most of AKSnowrider's clutching tips on here and WOW!!! That's why they call it a dragon
The next question is what RPMs should i be concerned with and start adding weights to keep them out of any danger zone?
Thanks!!!

keep it under 8500 when it hits 8500 it looses power..8350-8450 is where it runs best for me..havent been out yet so I dont know what effect the 010 update is going to have....

Any new info from anyone on what setups are working for them this year? Im trying the 62-42-.46 helix, SLP green/pink spring, 68g MTX weights with 2g tip and 1g belly as per AKSNOWRIDER next weekend in revelstoke and i cant wait. Ill be sure to let everyone know how this setup works

My friend and I both ran our dragons today after our updates. His is an 08 and mine is an 09. We both have an SLP single pipe and can. we are running slp's recommended clutching for 8-10 thousand feet. We are both lucky to pull 8100rpms on the trail. Running around 7800-7900 pulling a hill. We were thinking of going with no rivets in the tip and seeing what that does. Wondering if anyone else has done this on a similar set up. When I first got the sled it would pull 8250 stock. Kind of frustrating.
how high is revy? if its up over 5000 ft leave the tip weight off...if its over 7000 leave all weight off the mtx's... the 2 gram tip and 1 gram belly is what i run under 3000 ft..normally swap them(2 gram belly and 1 gram tip) for up to 5000 ..
