i have ulmer clutch kit for XTX. I used the stock spring (white) wrappet to 90 degres. nr 3 in secundary clutch and nr 6 in helix. And i think it was the way to go.

Nytro nr 1 :) but the arctic seems to run pretty good to, i think it was the launch control on nytro who made it.

okay, the stock hole then

anyone???????

Witch hole of the two is the softes on a xtx.

I haved checkt the data from my dealer (Sweden), and in the paper the center shock (in the boggie) has a spring rate off 1,5 kg/mm. The shorter rtx has 2,5kg/mm i beleve so it´s big difference.

Aihro helmets are great

do you mine less gap between the nuts and block. And the limiters strap in the top hole?
