1990 XT600 Engine, 1986 Carb
As the title says! Engine has 22K miles, the carb has 7K miles. The engine starts and runs, but has some minor, quietish backfiring throughout the rev range. I can feel puffs of air from the air intake when it backfires. I also feel it is running a little lean. Valves adjusted, Carb cleaned. PO removed the baffle from the exhaust.
What do you suggest I look at to possibly richen the mixture and secondly to eliminate the back firing throughout the rev range?
