Wanted to know from the experts, the advantage to doing a Coil Spring Clutch Conversion? I have changed fibers and metals and flat springs, but I got on it a little too hard and didn't give it a chance to wear in. So, therefore I have to go back in and check the fibers, metals and springs for wear. I was told I could make the conversion for less than doing a full cultch job and have better performance with OEM parts.
I have a 1990-1127 motor.

I run oem clutch plates in my 11. I also run a katana basket which has the coil springs and have never had any proublems. Im not sure as far as cost if it would be a cheaper set up or not. But it would make a big difference.

UK Lee I have a question for you. I have gotten all my parts for the spring clutch conversion and can't find a dam 10mm bearing anywhere!
but from reading your article the push rod is whats shorter. Can I use a push rod from a GS? I ran it by a guy I know and he says that the GS push rod is longer? I have no idea. Please advise.......

yup , the 10mm ball bearing is just there to take up the slack.

go get yourself some 6mm dia. tool steel bar , and make a new ( longer ) clutch push rod .
just cut it to length to get the required clutch action , and round the ends off. job done

UK don't mean to sound ignant, but whats the recommended length? I hate to go in and out of the thing if I don't have to, but we do what we must. When you said yup, that was to the push rod on the GS correct?

Thanks
