Going from 121 to 136, need clutching advice

[RX-Dave]

Taking my stock 05 121 RX-1 ER to 136 with a 1.375 paddle.

What should I start with for clutching and gearing.

I have a warrior 2ndary spring, and the rest is stock RX-1 clutching and gearing.

If I remember correctly, everyone was using the RX-1 Mtn. primary spring?

Turk, PLEASE HELP

Dave

I turned mine into a 136. with a 1" track and 164 studs. left it with stock gearing and a goodwin clutch kit and all is great!!!!!!!!

primary spring o/s/o mountian sled
change gearing to warrior
silver spring secondary twisted to 70 or 90
then play with helix's
pulls 10,400-10,500
i'm not sure what rollers are in the primary on a rx1 though

This is what I am thinking

New Dalton DPYR weights about 66 gr
OSO Spring
15mm rollers
Silver 2ndary spring
Dalton 54r42Helix ( I am not running studs)
silver spring with 70deg twist

what rollers came in the rx1?

I have not measured, some tell me the 05 has 15.5mm, but not sure.
