Working on a 2003 rancher 350fe purchased as a project put a new top end on it and noticed that the clutch was not working properly was only able to get up 35mph in 5th gear.

After pulling the motor and inspecting the centrifugal clutch I noticed some small grooves in the drum should I replace or just let it be. The list of parts going in while the engine is out is friction discs,one way bearing,timing chain. I can up load pics if needed.

Thanks for any input
