79cc predator, maxtorque ss clutch with bronze bushing

I know several people have made different types of modifications to centrifugal clutches, but idk if anything is possible for the SS clutch. I tried googling, but maybe I'm not using the right terms, every time I tried it gave me a bunch of results on torque converters. If what I want can't be done, please don't flame me. Also please do not comment on how bushing clutches are junk, its simply not going to be helpful. I'm looking for simple, helpful yes/no/how answers, not trying to go running down rabbit holes. So here is my question.

Can a bushing type clutch be modified or converted in any way, such as converted to a one way or be modified in such a way to pedal start? I remember reading on the other forum of a member modifying a centrifugal clutch (not sure which clutch or engine) to be able to pedal start, but don't remember reading how. If anyone knows how or can provide a link to the thread I'm referring to if they know, that would be great. I also remember that a member of the other forum, cobrafreak, created a bearing conversion mod, but don't know if its applicable to this type of clutch. If anyone knows and could tell me, that would be great. Just looking for any helpful info. Thanks.
 
Yeah but afaik those are special made just for the ezm for the qmatic. My maxtorque clutch is chain drive, so I'm not sure the one way bearing will fit or even where to get it.
 
I was wrong. It's the max torque clutches Quenton makes for the Whizzers that have the one way bearing not the EZ's.

NO.

A centrifugal clutch is a one way device.

The power output spins a set of shoes that spread out and grab the inside of a bell with RPM's to transfer power.
You can spin the bell all you want but it won't grab the clutch shoes and go the other way.
 
?????? Never heard of needle bearings or sprag bearings? They allow the drum to propel the bike forward when the shoes grab, but freewheel when the rpms drop below the engagement speed, thus no engine braking. The cent clutches in the two stroke engines have sprag bearings and some comet clutches have needle bearings. The only reason I didn't buy a clutch with a needle bearing in it is because they come with 12t sprockets, not 11t which would throw off my gear ratio. Your comment seems to assume that what I want is a clutch that will engage spinning in reverse. To be frank, that's just dumb. When pedal starting, the clutch is still spinning the same direction. Idk where you got the idea that I was trying to spin the clutch the other way. What I am basically looking for is a way to make my clutch freewheel when disengaged, so as to eliminate the engine braking. I might not have explained that in my first post, but jbcruisin understood exactly what I meant. Pedal start would be nice, but I mainly want to eliminate engine braking.

No, what you want is the fixed size clutch bell to somehow engage your engines clutch pads pedaling with the engine off so you can pedal start it. That is the dumb part.

Only the clutch shoes can transfer power in a cent clutch.
To do what you want, you need an entirely different automatic clutch system I have never heard of, or just go with a manual lever clutch and friction plate like 2-strokes do.

It is the same principle as a car with an automatic tranny, you can't bump start them like you can a manual either which is exactly why a 2-stroke with a cent clutch needs a pull start.

Clutches with one way bearings can be pedal started. There was also a guy on the other forum as I mentioned in my op who took a non pedal start clutch and modified it to engage when pedaling. I just don't know which clutch it was or how he did it. But as I expressed above and you conveniently ignored when quoting me, what I really want is a clutch that will freewheel to eliminate engine braking and yes, those do exist. How big is the rock you've been living under?
 
NO.

Not what I am looking for at all. If you don't understand the question, don't answer. Better to remain silent and be thought a fool, than to open ones mouth and remove all doubt.
