Low elevation clutching

[zoomer]

What should I run on my Apex Mtn at about 1400ft?

Please post everything I should change.


Then what could I do temporarily as far as leaving the stock spring and everything and just changing the clutch rivets? What could I change the rivets to (and only the rivets) to ride around here? Or is that even possible without changing springs or weights?

The primary set up is the 121 apex weights, never checked to see if the rivet weights were exactly the same or not, I think the primary spring was the 121 as well, 121 rollers I believe, same secondary spring, different helix. I run the stock gearing for high andlow elevation tops out about 95 at 2000' but gets there pretty quick.

What rivets are you running in your weights?

EDIT: TY Tech shows the Apex Mtn runs 8FS weights whereas the 121 runs 8FP weights.

does this help at all? im running mine according to this chart but will be changing gearing to 20/40 68link chain

I have this chart, which is a little bit different, as far as the weights go. I might just get some 17.2 w/holes and a 17.2 and load up the clutch weight and not change my primary spring and see how it work.s

Im at 1900 feet in South Dakota.
I use all the high elevation hardware and load the weights with the heaviest rivets you can get and wrap the secondary spring to 70 degrees. Runs 10800 flat out.

I have the same page as zoomer, @ 2000' it runs 11000 on trail, 10500 in real snow.

Gonna load the weights up tomorrow, and why do you wrap the secondary to that? And how do I tell its 70 degrees? I've never messed with a secondary.

outside on the secondary the numbers are easy to see...i took pic of inside secondary for the above post...mine is set back to 70 (1-6)

Thanks. And I see on my chart that the secondary should already be set at 70 degrees. So I should be good to go on that, but I'll double check it.

Loaded my weights up with 3 17.2 solids, and it runs about 10800-11000 wide open, left everything else stock.
