Anyone possibly give able to give me an idea on where the Co settings should be?my bike has had the Leo vince exhaust and stage 2 air filter mod done. Im assuming that no Co settings were changed when the changes were done to the bike.I’m getting backfires when tapping off at low rpm, and she doesn’t enjoy lower rpm riding. I have the Yamaha FI diagnostics tool which was set to 18 on the Co setting. Any advice?
