Top Speed Runs NA VIPER

Almost... Be careful with all the New Year, KNUCKLEHEADS. Not enough snow in my neighborhood to have fun yet.
I know. Storming alot up there so that and the bars will hopefully keep them off the trails at least in mornings!
 
When you get different weights, try getting the rpms down to 8800ish. 9200ish Im pretty sure is like a soft rev limiter. Starts to pull timing before the actual limiter.

My Nytro was quite a bit faster/quicker running those rpms vs above 9000.
 
Right now. Orange yellow orange primary spring,D&D Magnaforce wieghts,Stock spring in secondary with a Dalton? 50/40 helix at 6-1.
Orange yellow orange? Which brand is it? What is the spring rate?

Doss your sled have a engagement stutter setup?
Yes. Ulmer PCV and ignition. Pod300 and setup with stutter and two map switch. I have tweaked the fuel maps myself but pretty close to way Ulmer sent them. Might play a bit with ignition yet.
 
Depending on that spring rate.... Your making power, and rolling resistance is low. Because fully loaded magnaforce weights is pretty impressive.
 
Maybe this is the best mod of all. Sure had a ton of fun doing it. Happy New Years TY!

Gotta love the Gypsy Pointing System. Is your water temp 199 ? Congrats on the 10,000.

Yup 199 from idling and 1/4in sheet of ice over radiator most of day. Perfect storm of sno dust from slower sleds and very heavy lake effect with temps around 0 f had to chip it off twice. Forms on grill not rad itself. Once off drops instantly.
