blackbird2xx Posted April 11, 2010 I have a 77 yz80 engine in my ysr race bike, and I have carb issues and questions. First the questions. What size is the STOCK carb for a 77 yz80? Second for you old school dirt racers out there what is the best carb to make this engine come alive? Now on to the issues. The shop that did the rebuild on this engine broke a reed cage bolt, so how can I get the broken half out??? Thanks Share this post Link to post Share on other sites
