Hello,
A friend of mine is putting in a new top end in his 99 RM 125. From his past engine building experience, he believes he should hone the cylinder before he puts in his new piston and rings. He says it's for removing the "glaze" on the cylinder wall, which will help the new rings to seat better. Should he do it or not? I know he could get away with it either way, but which would be better in terms of performance and longevity of piston/rings? Is it worth the cost?
Thanks a million in advance.
