Adjusting valves
#2
#4
Valve clearances were one thing that the old 425 and 500 were pretty good about. Intake valves are the ones that most people do have to adjust over time as the valves are a lot softer than the exhaust valves and do cup from wear which decreases clearance. Same can be said for most 4 stroke engines. I've had some 5 or 6 years old that came in for service and clearances were still spot on at .006 intake and exhaust,but every engine is different.
