TRS Clutching [ PART FOUR ]

[TRS]

What is the pro NA setup? I have the 46/34F in there noe with a 100-200 spring. Stock gold om primary with 70 Lightning and pillede one Thon shim (not sure I'm done there).

Pulls strong! but only reaches 7950-8000 and IT surges forward even og engagement is smooth.

Have pro gears to put on, but wonder if 68gr weights and a slightly shallower helix Are in order?

This is for a 13-15 for 8-10,000' , stock belt drive, 163 track
54 34 .46 ER or .36 ER
120-220 Red/Green secondary spring
140-330 Stock Polaris primary spring
60 gr Lightning weights
If you had your sheaves machined use the Polaris 120-310 primary spring


Testing
46-32F
100-150 red/yellow secondary spring
110-290 Polaris Primary spring
59gr. Lightning weights
This is not for a heavy weight rider.( -200#)

You must set your center to center 11.5" and lead in set to .00"-.020".

The cut sheeves match the Axys primary correct?

Generally, but depends on who cut them. I can't give proprietary secrets away.

K... Sorry, I asked the question wrong as usual.

On the Pro set-up, which I haven't verified, but believe it's what you listed..... The cut primary utilizes a different primary spring. Is it angle or cut primary's in general???

It's the cut primary, engagement increases with the AXYS or cut primary. The initial angle change at the bottom from around 12* to roughly 13.5*.

Went out last week with complete TRS setup. Checked temps after along hard pull in heavier spring snow. Turned out and got down to the bottom of the hill fairly quick, then immediately checked temps with a infrared heat gun. Primary 100 degrees secondary 110 and belt 140.

Have you used a heat gun on your previous clutch setup??

No I have not. I posted what I found to see what others thought of those numbers. Ive been running it pretty hard with no belt failure.

Gotcha, curious what stock temps are now...Never used a heat gun on clutches while out in the mountains before. Nice to see comparisons.

72.5g lightning weights on Ebay

They are hard to find. I bought 1 set for myself. 1 set left.

If anyone knows where I can get my hands on some 60 gram lightning weights please let me know.

Is the 2 cut indy dan mountain helix the NA helix with high and low elevation. I have that helix and his turbo helix, anyone know the difference? I set the h/l helix to the side when I got the turbo helix. I am lacking down low snap, too much lag. I am trying to figure out if it is my clutching or the fact I have a big 2873 turbo on a mtntk tune.

 

[aksledjunkie]

His helix cuts that he sent to us were single cut X1 and X2. Two separate helix's. The X1 was shallower than the X2 if I remember correctly. I preferred the X1 over the X2. Allowing to run lower valued springs.
Pretty sure during testing I noticed a lag with the X2 but when it hit, it hit like a damn freight train and just pulled hard.
The X1 was much more linear. It was similar characteristics going from the T1 weights to the T3 weights. I preferred the T3 by far.

TRS; could you recommend me a setup for a team tied clutch. Im running Indy speciality's turbo weights up front.


56-46F (should compare to ~42-32F), or do you have some other experience with angles on tied? Just read that the general rule of thumb is TSS04 angles + 14 = tied angles.


Secondary spring?


Cheers

No recommendation for the tied. I gave up on the tied clutch long ago. It was not worth investing large amounts of capital to try and out perform the 04.
There is more performance to be had with clutch alignment and offset.

I would love to see a setup that compares to this that does not require belt to sheave to be adjusted.

 

[RFleck17105]

I’m running a 17 axys with the MTNTK turbo kit and want to improve clutching. I ride from 7000 feet to 11000 feet. What springs, helix, and weights do I need to improve this kit?

 

[562xp]

This will give you a general idea of where to start.

As always - the big question is where to buy the Lightening weights at. Anyone? Any reasonable subs at this point?

What I'd really like to find, again, is a similar setup using Polaris's 10 series profile (no shimming) but guessing that isn't going to work.

I read somewhere that Indy Specialty had some lightning weights made recently.
