Axys 174 sidekick clutching issue.

Working on the shops 174 turbo. 5lbs of boost. Ridding 6k-10k ft. Has BD recommended clutching. Almond spring and 68g weights. Problem is. It had like a stutter, or chatter per say at low speeds. (like a bad belt) And it kinda "snaps" (grabs hard) when it first engages. I called BD about it and they said my main spring was bad. It does have a little wear on it. But it's just so hard to Beleave that a brand new clutch set up with less than 200miles ruined a main spring. Any opinions? Should I order a new spring. Thoughts about going to to a little softer/harder main spring.


Also: Checked the rollers and weights. No issues.

We put a new belt on tonight. Didn't see any burn marks but like the whole belt was glazed over. Thinking they didn't let the belt brake in. New belt and I ran it while it was lifted to watch the primary and see when/how it engaged. Should have done that to start for a comparison. Seems to be okay now with a belt. Have to see how it rides Sunday and decide If I want to play with the clutching or not.
