Tightness for valves on D16Y8
 

The manual calls for 0.007" and 0.009" for the valve adjustment...forgot if thats the exact number but anyways

just wanted to know if i should set the valves to the specs in the manual or can i get better performance from making the valves slightly tighter?

set them to the specs if you go tighter you risk issues and see no gains

ya ill probably do that...but i think the manual gives a range something like .007" to .009"...........should i go closer to the tighter side of that range?

aim for 0.008" then if your off you have clearance both ways
