clutching questions

So I am working on a 2003 polaris vertical edge with a 159 track on it. Ive been working in it for some time now with not what I would want results. I weigh about 275 lbs. I am running about 7 to 9000 feet, I have twin slp pipes motor is strong with good compression, I did a top end last year. At the moment I am running a 21/41 gearing with 58 gram weights and a 140/340 spring in the primary, I am running a slp yellow/purple spring in a button style secondary clutch. It doesnt feel like I am getting the track speed that my families sleds are getting. They all have faster sleds and can climb as far if not farther than mine. It feels like mine is in a lower gear. We have switched sleds and mine still loses with lighter people on it. I have tried 19/43 and 19/41 with 60 gran weights still felt not right, but what I am running now seems to be the best so far. I am hitting about 8100 rpms. If I mark my primary clutch with a sharpie how far out should the belt come out? And should I mark my secondary also? Also if I am hitting the right rpms on the top does that mean my clutches have shifted out? Any help is greatly appreciated.

Re: clutching questions

Go taller like a bigger on top or smaller on bottom? Will I be able to pull it. When I went from 19/41 to 21/41 I couldnt pull my 60s had to go to 58s

Mark both units.
They should wear off all the way on the primary and to be curve at the bottom of the secondary sheave.

If they don't wear it all off, then you have a little adjusting to do.

Re: clutching questions

If I dont get all the way out on the primary or in all the way on secondary what do I adjust to bring it out. If im hitting rpms do I adjust secondary tension? Or just what?

Partly depends on you belt too, is it new?
If the primary is just missing say 1/8" of the outer edge, then it's good, but you want the secondary to polish clean which means you may have to adjust it's opening width a bit.

Re: clutching questions

No belt isnt new but in good shape. I would assume if I dont get in all the way on the secondary I wont get out all the way on primary right? On a polaris button clutch how do I adjust opening width the only thing o see on it is a dial on the front from 1 to 5 is that what I adjust?

That is correct.
You want the top edge of the belt 1/8" out of the sheaves.

Re: clutching questions

Ok great. What about the spring inside the secondary, will tension or hole position or spring color affect how far the belt goes in?

Moving that plate on the outside will take care of that.
And, yes, spring load rating and anchor hole placement will affect shift out as will helix angle.

Re: clutching questions

Ok great thanks for your help. Can I mark the clutches at home and put it in a stand to see how far In the belt is going I live at about 4500 feet, ir do I need to check it at the elevation I ride at with me on it? Also on the clitch side of the motor there is a little push arm that looks like you could move the motor and primary further away or closer to the secondary, is there a center to center measurement from crank to jackshaft?

That's a torque arm to hold the motor in place solid. There is a center to center distance i think an 080 belt is 11.5 inches

And at 7-9k ft i ran a couple sizes leaner i found that slp was on the very safe side with jetting for the twins

Can I mark the clutches and run it on the stand at home or do I need to be on it where I ride to see how far the belt goes in?
