What a different animal.

Holy cow had the local shop put in some original heelclickers in the new pro 800 155 and a 19tooth top gear what a difference it made it pulls very hard on the bottom and mid now but thinking to much. dont know how the weights are set up but i know the primary spring is a 170-360 spring and the secondary is stock witch i believe the black/purple and the 56-42-36 helix. It pulled 8200 rpms at the normal riding spots of 3000-6000ft. Lookin to have less tractor pull feel, don't mind the engagement maybe more upshift wondering if a steeper helix might be the way to go something like a 60/40/36. Also I dont understand how to read the helixs posted on slp site example LW Helix, 58-38ER.36 / 58-40ER.36. Is that helix a -38ER on fullshift out or a -40ER. You guys think a helix or did they not put the correct weights in or are my way off track any help will be appreciated thanks!!..

The way the helix reads is for example a 60-40-.36 would be it starts out at 60 degrees for .36 inches and then after the .36 inches it is 40 degrees the rest of the cut. Most helixes can be installed in 2 different positions. You will notice 2 sets of numbers on the back. The stock helix in a pro only has one cut in it, so it can only be installed one way. Also the ER just meens its a helix cut with the reverse notch in it for sleds with reverse.

First you need to tell us what weights are in your primary.

I'm riding in 3K - 6K like you and have 62g Belly busters with a stock primary spring on milled down sheaves
On the secondary, I run a 62/42.36 ER with team Gold/Blk (175/240)

Well thanks for the help guys I finally talked to the mechanic and he said he had put 64 gram arm weight in the primary if that helps anymore.

I would start... with the Spring ....

Weights are ok!

maybe try a slp spring

140/340 Blue Pink! Part # 40-76

Thanks napa matt.

I seem to be reading that when they go to a stiffer spring in the secondary it seems like the black/purple might be the way to go but when I look up what the my sled has for a secondary spring it says black purple from wedsite http://parts.polarisind.com/Browse/Browse.asp ??? Can somebody shed some light.
