Hi all.

This week my RKT Head/Pistons/Base Shims will be arriving. I also had Kelsey do his intake mod(same as DNE mod). So im looking for some baseline advice.

What I have: 02 SD MXZ800 Renegade w/DPM w/RER
stock clutching consists of: Primary
violet/yellow spring
301 ramps
pins 16.7g

Secondary
purple(violet?) spring
47/44 RER helix


Only other mods added....V-Force3 Reeds and HPS stinger. Pipe is stock. Rider weight 280lbs. Looking for advice for aggressive trail riding...corner to corner speed is important.....speeds over 85mph not a priority. Typical elevation 0-2500/3000 ft. I will be using 92 octane pump fuel.

Any input will be appreciated. Kelsey was good to deal with but he was honest about not knowing how to clutch flatlander MXZ's.

TIA
Todd

Ask Big John over on snowest forum. He is a clutching god!

A good starting place is :

17.5 gr pins
200-320 primary spring
50-46 helix
clicker 4-5

good luck

GLHRACING what do you think of maybe 230/410 primary, 297's with 19 grams of pin, the helix you suggested, a beige at b-6? more power with his mods. i have great respect for your opinions, just pooling thaughts with you to help out.
