Hello guys….who has a advice.!!!.GSX R 750 W..after cylinder head seal change has completely narrowed down the valve play…think have committed some montage error….. I have all numbered the cup keys in bags inclusive the Shims ……after renewing the cylinder head seal the cylinder head again completes…Shims and the cup studs again on your old place… camshafts built in…Control times exactly ..chain tensioner in..click Click…… .with a few times in driving direction until OT turned again and the corresponding valve inlet outlet tested…….whether inlet or outlet everywhere too tight! outlet all about 0.08 mm and inlet also no longer 0.06 about………. should have inlet between 0.10 and 0.20 mm and outlet between 0.20 and 0.30 mm…but you know that….only I wonder…what did I do wrong! …oil between the Shims?…that would have to be pressed out at a few revolutions… according to the manual…… .!?!
