Kevin, Do you have to run the clutch with the drive sprocket “outboard” in order to clear the chassis properly? From what I have seen since we got our WF many years ago, the general consensus is that running it “inboard” places considerably less strain on the crank and drive-side bearing.
I’ve heard that – to do that on this kart, I’d have to remove some of the unused (currently) middle axle bearing bracket. That would be easy to do, though – I might try that when the new clutch arrives.
