I am wondering what other clutches fit the Honda copy 253FMM engine. I know it's basically the same as the 244FMI and many parts are interchangeable but I want to fit a six spring clutch to my engine. I have seen pictures of clutches for CG and others that look like they would fit but I don't know for sure.

I am doing a bit of experimental work on my engines and have already made a 205cc engine by fitting YX140 pistons in a shortened 253 barrel to a Jinlun 244FMI bottom end, using an AJS Regal Raptor 125 head for higher compression and it works very well. On that engine I also converted the standard Jinlun 180 degree crank to a 360 crank for single carb use. Now I am wanting a much stronger clutch than the normal 4 spring one found on most of these Honda twin clones. Can I just put the internal bits of for instance a CG250 clutch into my standard clutch basket?
