Hi Guys,
I've had a bit of trouble with my transmission on my '85XR600R. It seems that the C5 gear has lost one of the engagement dogs. I found another at the local salvage yard but it is about an 1/8 inch less wide than the one that broke. Everything else is the same on the C5 gear. The opposing gear it meshes is also a little different to accomodate the thinner C5. The problem now is that the shift drum doesn't throw the shift fork far enough to fully engage this "new" gear pair. Both shift drums are identical so thats not the problem! Is this what everyone says that the XR trans had problems with and am I trying to replace it with the "fixed" gear? What else did they change and how do I fix? It is actually the second gear pair that I'm having trouble with. Did they change the countershaft a little to accomodate the thinner gear? It looks the same as the original. By the way, getting into an XR trans is no fun, especially the second or third time...
