Has anyone ever experimented with increasing the diameter of the transaxle clutch cable pulley?
Obviously the housing would have to be modified that much goes without saying. My wondering on this idea would be to shorten the "throw" at the pedal with the hope of increasing shift speed (I've converted to a cable shift). Direct experience with this modification very much sought. |

Hey guys , just a thought. You are effectively shortening the cable length, so why not just tighten the cable to preload the clutch to the point you desire. Anything you would do would have a diminished rate of return.

Anything you would do would have a diminished rate of return. True! I tried this by adding a spacer between the adjuster and the fork rod end but unfortunately, any preload (in this sbc application) was disallowing the clutch to fully disengage thus making for a clutch slip under hard acceleration. That said, more tinkering (size changes) may yield a result. Would it ultimately shorten the throw? I have doubts it would be noticable. |
