So I decided to re-tune and sync the carbs on my 79’ today because, since I finished this build and initially tuned and synced the carbs, the left cylinder seems to run smooth and the right cylinder just seems to not be running as smooth. It runs, but just not with the same steady cadence as the left cylinder. Before I initially tuned the carbs (only like 40 miles ago) I adjusted everything else (timing, cam chain, etc.) first like you’re supposed to. Now just so you know, this bike is running open headers and pod filters. So I’m running #130 pilot jets (one size up from stock #127.5) and a larger main. When I actually got to the carbs, I set the mix screws at the stock turn out, and then adjusted the by sound from there. I DID NOT use the carb guide method at that time......yet. So with the right cylinder starting to annoy me, I decided to start over and use the carb guide method to see if it would enlighten me as to what may be going on. So I do the the left cylinder/left carb first. Everything goes well and I’m able to find the sweet spot as I use the carb guide method which was probably at about a half turn in from the stock mix screw setting with the larger pilot jet. Then I move to the right cylinder/carb. I start to go through the carb guide method and I start to find that the more I lean/screw-in the mix screw, the faster my idle goes. So I keep adjusting the the throttle stop screw accordingly and then go back to the mix screw. To make a long story short, I literally was able to adjust the mix screw ALL THE WAY IN and still run a fast idle on only the right cylinder! I’m no genius, but at this time I’m thinking I may be onto whatever my issue is with the right cylinder. So obviously the right was running like shit before because it was running rich when I had the mix screw out about 2.25 turns on my initial tuning job because something’s not right with the right side mix screw. So what could the issue be? I’m thinking either my right side mix screw needs to be replaced or, and hopefully this isn’t the case, the carb body is damaged around the mix screw somewhere. Has anyone else had this? Is there something else that could be causing this?
