Primary Engagement

[Radar78]

I’d like to find a primary spring for my daughters 07 M6 that allows for a smoother, lower RPM, engagement over stock. Any suggestions?

I would start with a spring that has a softer start rate. Likely 20-40 lbs softer than what it currently has. Also check for worn parts particularly bushings while you have it apart. Most M-series I've ridden have a sharp engagement and it certainly isn't nice.

A Dalton white/green solved it on my M8. Smooth as silk now. They probably have something for the M7 too.

I believe back in the day the AC gold spring was what everyone used.
