Mcx clutch questions

[TNytro]

Finally i´m about to mount the mcx kit on the Nytro. Now the thing that worries me is the clutches, i´m starting with 68g heavy hitters in the primary and the stiffest yamaha spring in the secondary.Thats all i know. I run a 162 extreme with 20/40 gearing at 0-3000 feet. Where do i start weightwise in the primary? thanks in advance.

Here is what I am running:
Blue/White/Blue primary spring
8Bu-00 weights loaded 48.7+17grams=68.7grams
14.5 Rollers

Pink spring wound to 90 degrees
45 degree helix

MCX 14 psi boost in the mountains 11psi boost at 1500-2000 feeet

the primary should be a good start adjust wieght as needed, secondary needs to be 100-110 and 47 degree helix. or epi purple at 1-0. the 45 helix will work but a 47 will work much better.

Just buy a Shockwave helix if you can get one, that way you have all the helix angles and can fine tune for conditions. Most guys are running 8BU-00 weights with a couple of 4.5g pins in each. I like a 4.5 and a 3.6 in each for around 12-13lbs. I like my motor to run at 87-8800.
