i know im resurrecting an old post but ive got a spare clutch and i want to do this mod.
my present clutch bites at about 5-6k but only because the material has almost worn off the leafs and i am getting sparks. looks great at night. ill have to do a video.
but it aint gonna last long so i want to do this.
in the time that has passed have you (or anyone else) modified or improved this mod?
i havent got a lathe but i can tig weld and have grinders.
like someone else posted maybe a backing plate using the 4 original tiny screw holes and several spring anchor holes in it easily vary spring tension?
im off in my shed now. i may be some time......
