Backshifting Problem

[usher]

Ive got a 05 M7 and I am having backshifting problems around home. Im running 75 gram and a Team "Orange" primary spring and nothing in the secondary as far as i know. Elevation around home is about 2200 - 2300 feet. I called the one cat dealer and they said to try a D&D torsion kit. I would rather just change the spring or helix and not have to screw around with settings to get what I want and not waste the money if its not going to change much. What should I do or what other options do I have to fix the problem??

Thanks

It might not be in the secondary..I've seen 3 primary's sticking partially closed and then the belt gets swallowed in the secondary....

and what causes that ?

Also check your secondary rollers and the helix surface. We had one that wouldn't backshift even after replacing the rollers because of the scuffing on the helix from a bad roller. Knocked down the scuff marks with some emery and it worked fine again.

Primary rollers and buttons,also the bushing on the outer sheave,(gets gummed up)..
