my clutch setup (dalton)

[WinterWolf]

I'll chime in here with my thoughts on your questions. With your current clutching set up you're running a little low on your target rpms. A long time clutch tuning rule is to use your primary clutch to control top rpms and not your secondary clutch.

You'll probably gain a slight top rpm gain increasing the wrap on your secondary spring from your current setting of 3-3 to the 6-1 setting that seems to be the recommended setting for your Dalton B/O spring but probably not enough to get you where you want to be.

I would go ahead and set your wrap to the 6-1 setting like you mentioned doing and consider taking your stock weights out of the clutch and replacing the rivet on each weight near the tip of the weight with a lighter rivet to get your top end rpms where they need to be. It's going to take a little more time/effort to due this but it should be the easiest/cheapest route for you to get where you need to be without the added cost of going to the easy to tune and more expensive aftermarket weights.

It's cool to follow your clutching progress on your sled using the stock weight set up with aftermarket only secondary changes. Hopefully this helps.

Thanks for the reply VX.

Being stock drive clutch and stock components, you would think it should be set up to reach target R’s right from factory.

But I’m certainly going to move the wrap to 6-1 and see where that leads me..I think that it will be a good thing like Joe found.
At 417 miles, Sleds not even broken in completely yet...so I’m gonna wait until I have about a thousand miles on it to see where the R’s settle at at that point. R’s seem to be coming up with the more miles I put on too.

I would start with a known good baseline. That spring we also recommend 6-1 to get similar torsion to the stock spring at 3-3

You don’t need a reverse angle helix with a tune. My 2 cents.

If you want one I have a dalton 35/39 in the classifieds.

I have one in now and seems to be working pretty good but don't have much, or anyone to compare

yesterday i got the chance to put on 75 miles of lake running on my max spool 17 td tuned sled .
primary clutch - dalton weights 79 grams
dalton primary spring /blk -grn . 3800 engagement . 2 glide washers
secondary clutch - blk /orange @ 6-1 spring or 70
dalton 35 helix , td rollers .
yamha 8j belt
this combination works great. all day rpms were 8900-9000 . clutch r cool , very little belt dust ,
yesterday ice condition were very fast and hard , the max tune is so aggressive that i was hooking so hard on the ice it pulled out over a dozen studs out the track . this tune is wicked .
with hooking this hard u would think the clutch may show some sign of belt slippage or belt dust , everything was perfect , only need a new track now .

where did you have your set screws in your ramps,i have same ramps from dale,and when I checked them on my digital scales empty,if I remember they were 74.1 empty,and I added the 2 gram screw,and screwed it to tip,but you can make them stay anywhere you want in the hole,from heel to tip. So how are yours loaded. Thanks

the heel

the heel

So that I understand you correctly,your base weight close to 75 and you set them up to 79 grms,correct? And you loaded just the heel? And that you added 4 plus grm screw. Did you leave the tail of it,even with the very back of heel? Or sink it in a few threads? Thanks for the info.
