The clutch system on these engines is rather simple, and for some people it takes a bit of strength to disengage the clutch. I remember when I first let my girlfriend ride my MB and she had a difficult time operating the clutch handle. This mod should help solve that problem. I've seen/heard of clutch pulleys before, but they either involved welding or modding the clutch cover. With this hack, all you can make your own pulley from hardware store parts! The only thing I might do when I make one of these would be to find a way to fasten the clutch cord tube to the bar rather than using JB Weld, but JB Weld usually holds up nicely anyway.
You can also buy a similar prebuilt clutch pulley(aka roller bracket) from Al.Fisherman!
