I was wondering if anyone is running a different primary spring with no shims at all? The V Force comes with a shim under the stock primary spring. Can you run a HPD plain spring without the shim or will no shims hurt the clutch where the spring comes in contact with it? Thanks......

 

You can run without the shim. Some people leave the shim in to give a bit more stall and shiftout. Mine had no shim from the factory.

 

Okay thanks for the reply 4wheels.....
