hi , I have a 2000 yamaha sx 600 r with red heads . The sled keeps losing its fuel even with a new pump on her , she ran great for a few hours after I replaced the pump the next day went to go for a run with her made it about half a mile and she started to back fire again . Checked the cylinders the seem ok lots of compression , but belt side wasnt getting hot , so took everything off clean it , put it all back together and everything repeated agin but it jumped to the belt side not getting effort fuel , help help :sled1:

try cleaning the flywheel. the trigger sensor picks up on the outside on those and any rust on the flywheel causes weak spark and the issue you are having.
