Manual clutch 90, is it possible?

[90nut]

I want to convert my atc 90 into a manual clutch. Anyone seen this or actually have done this before? Any help or ideas would be great.

youd have to use a different engine (to make it easier) but ya it can be done. I think there was a link here a littl while ago of a guy on ebay that had like a 110 dirt bike engine in a 70, and that was manual.
