Is anyone running the stock clutch spring with the AIM clutch and a 107 build? I had the 107 FM kit done last year and FM installed the heavy spring to hold the added power. This year I purchased the AIM clutch from FM and was told to keep the heavy spring in there. The clutch pull is ridiculous. I want an easier pull and read the AIM directions that said it would handle 130/130 with the stock spring.

I posted this here because there are few readers in the clutch section. Any replies from those that are running the above combination would be appreciated.

 

I initially just had a S/E clutch spring in my build. When looked at graph on dyno, I saw that there were several drops in the torque curve. I decided to add S/E VPC. When I removed the derby cover there was a strong odor of burnt clutch syndrome. Decides to change the primary oil also. After thinking about it for a while, decided on changing clutch plates (S/E again).As far as pulling hard, only when the rpm's are up can I tell it pulls harder. If you're wondering why all S/E parts (I have my perks). If I would've done it all over I would've installed a complete Bandit Clutch.
