I'm working on a '95 YZ250 project bike. 5th gear was seized up solid on the main shaft. Everything else looks just dandy. Question for you guys that know- just out of curiosity; could a good machine shop turn the main shaft and gear to accept a bronze bushing? Is that even a thing or is that a lame idea? Yes, I'm going to replace it but the thought popped into my head so I just thought I'd ask.
