08 turbo nytro clutching

clutching

I'm certainly no expert but heres what works in my Nytro @ 12 psi 2000'...

Primary:
8Bu-00's Fully Loaded
14.5mm Rollers
Blue/White/Blue Primary spring

Secondary:
Shockwave Helix
EPI Purple Spring Wraped 0-1
start at 1.5 turns out

a lot of boosted yammies are running a green Arctic cat secondary spring , blue white blue yammy primary spring , 14.5 mm rollers , either dalton adjustable weights or the fully loaded 8BU's, a 49 degree helix or a shockwave. The shockwave and daltons is the way to go , you will have a ton of adjustability with both.

Ahh the clutching debate

MCX 180 2.5 x 162 track worked good at 1600' and 6500'
Primary
STM weight's 74 grams total with the two 7 gram tungsten's in the base
Blue Brown Blue yam spring
stk 16.5 rollers

Secondary
purple epi spring set at 1-0
45 deg Dalton helix

With this set up it will tap the rev limiter from a dead stop then smooth right out at 8800 back shift when needed and work greet. I am going to try a 50/44 dalton R series helix this year they are not a equal split, steep the first 20%ish should be ideal for boosted sleds, guess I will find out. I tried the Dalton -2 weights they were to much empty with the stock secondary setup, the lighter set may work but the STM's have more adjustment if your buying a set. Lots of diff setups out there, I came from cat so the diff Yam weights and roller combo's ? I will stick with one profile and roller to sort it out.
