I always have the service manual within reach, but it didn't touch on the removal or installation. It might've been feasible if I had removed the reed block as well. The fact that you've never had to do it speaks for itself as to how great these old 175s are. They are my favorites. I have one from 70, 71, 75,and 76. And I am ALWAYS in the market to fill in the missing years. I also have a 77 which turned out to be a Frankenstein bike with an MX125 engine. Oh well. Nothing is exempt from my Yamaha Rescue Shelter. 🤓
Good question Schu, but even though I have one of these bikes, I've never had to do that ... so naturally, I can't say.
Have you checked the service manual in the sites digital library?
It may say something about that, but I kinda doubt it.
Might be hard to find someone with experience on that particular question ... those 76 models are kinda rare.
