That is the only way the YS line will perform for me. I have found that a loose valve setting breaks E-clips and rocker shafts.

You probably shouldn't use a feeler gauge unless the engine has never been run.
The reason is as the engine runs, the valve stem starts 'peening' a dimple into the rocker arm.
If you put a feeler gauge into a well run engine and then adjust the valve, the clearance will be way too loose.
IMO, the correct way to do this is to adjust the valve without a gauge for just a slight amount of free play when you
move the rocker arm

Hello all, I have a silly question, what is the gapping on the YS120FZ. I have set the valves before, but do not remember what the gap should be.
TIA
Thank you
Anthony
