That looks better. The skirts are very tight on a Honda. Is there any lip at the top of the bores, pics please
OK, they need to be honed out until the lip is visible no more. Then you can get a true measurement I know what all the books say to the max spec but, when this engine was new, the piston to bore clearance was tight and when I mean tight, less than 1 thou.
Loving your upside down pics, is it a Derbyshire thing? 😀😀😀
Checked the valves over tonight..looks like they and the guides will need replacing they failed on both the valve guide clearance and vertical run out measurements...by a large margin! doh! 😕 On a more positive note the springs are ok! 😊

These will need re facing
