Hello Cb750 owners
i am over here in the uk and really need some help with my rebuild. I have spent a small fortune on this engine only to find that the duplex primary drive sprocket teeth on the cush drive (clutch end) are worn to a point and therefore no good? I can get primary chains easily over here but i cant get a primary sprocket / cush drive anywherer, even used. I have been looking for months and really am at my wits end. Can anybody help with advice on where i can get one or what to do???
Thanks in advance
Ian

Maybe post a pic here. Those sprocket teeth are usually pointed, all may not be lost afterall!

Well CMS doesn't have them.....

Did you check Honda?

thanks for the quick responses. I will post a picture this afternoon of the sprockets, you reckon they are pointed anyway? no flat top on the teeth crown. Why is that?? Anyway i will post a picture and see wha you think.
thanks
Ian
