yeah ive got a guy going bananas at me saying i need to do a full 300-500 break in at low rpm

but that will stuff the rings up mate
NO YOU MUST

haha.

anyways, i ran the piston over a stone, dingleballed the cylinder
actually measured the cylinder and piston by diggin out my dusty bore gauges
and its now slighlty over the minimum clearance, so its self clearanced nicely

gn125 minimum 0.03 to 0.051, dr200 minimum 0.04 to 0.05mm - max 0.12mm
i measure 0.55 so i think im good


going to put it back in and immediately redline it through every shift
