Please help!! 4 stroke centrifugal clutch

[meridianPeteJ]

First off whats wrong with the clutch that came with motor and if you bought more clutches you might be able to take the outer part with sprocket off and slide on one of the new clutches you have. You need to find other post with the motor like yours cause I believe he thought his clutch was bad to but I think he just needed to adjust valve clearance.

Did anyone notice that she is not pointing out any particular problem she is having, only that she wants either a centrifugal clutch that will fit or a torque converter...She has given zero reason why it is needed.

I think that is the first question that needs to be answered, especially as she says she knows absolutely nothing about motors or how they work...That being the case, she would not be knowing what centrifugal clutch or a torque converter would do either.

It also looks like a brand new motor so if there is a problem, what is it before any real advice can be given.

Right now the holidays are upon us. If the OP hasn't posted again after New Year, then she probably isn't going to anymore.

Help with 100cc 4 stroke

Hi, I’m running a 100cc Chinese 4 stroke kit and really struggling. The clutch burnt-up and the engine started shaking really bad. It has always knocked and ticked since new, but I’m thinking it’s basically done. It appears to be the same engine as the Predator 79cc engine you can buy on Harbor...

It's been a little over 13 hours......

I think I will stick with my little 2 strokes, those speeds on those 4 strokers are just waaaay too slow for me, even at my age...lol...lol.

I agree. The appealing part of 4 stroke bikes is reliability

So I'm going to get a set of calipers tonight, that will definitely help me figure out the size and give me more of an idea of what to get. Really want to switch to the torque converter, the clutch is ok but I'm constantly having to lubricate the bushing what seems like an awful lot. I'm doing a lot of research and I'm having a lot of trouble finding info on this type of engine and style. Of course I had to ask for one that goes faster! Lol jeeze! I am really enjoying learning about all of this and about how the engine works! Definitely something I never thought I would be learning but glad I am. More girls need to know this type of stuff!

Its pretty much a one of a kind motor and I have looked before for parts for it cause I wanted one of those drive units and I cant find any parts or who sells them. You can find tons of torque converters and clutches everywhere but you need to know shaft size and bolt pattern.
Good news is is that it looks a lot like a harbor freight Predator 79cc. Hope that helps a little

I know one good thing about them is you can sit at a stop light for hours with them running and not worry about them getting hot. At least with a predator 79 or 212 you can.

Well once you get it measured we can go from there. So are you looking for ease of installation with little maintenance? A more powerful engine that would still fit your frame might be hard to find. Maybe a honda gx100.

If you put a torque converter on it you can put a smaller sprocket on the rear wheel to increase top speed. Do you have any hills around you that you bike needs to pull up?
