Hi all Using a guide for valve clearances, seems pretty handy https://themcdonalds.net/richard/wp/zx-6r-maintenance-adjust-valve-clearances/ Couple things i need to clarify: The TDC marks for 1/4 and 2/3 - at 1/4, either cylinder 1 OR 4 is at TDC, rotating a full turn to 1/4 again will put the other cylinder at TDC? Is that correct? - when at TDC, both pairs of inlet and exhaust valves can be measured (4 valves altogether)? I've been looking through the forums just cant seem to find this bit of detail. Praying i dont need to do the shims but not confident haha Cheers!
