Nope, just the reflection. When you measure a cylinder you should measure inside the ring groove too.
The groove in that cylinder looks worse than it is. I should get 2-3 more rebuilds on it before it will need attention. That cylinder was only out of round 0.001 from top to bottom.

Hi everyone Correct me if I'm wrong about a top end rebuild. Its been my understanding that any cylinder that has been chromed, nikasil, plated ect.. is not to be honed? Is this correct?

It should be honed but do it quickly as not to eat through the plating.

Well I just had a issue with my rebuild. I got my Wiseco top end kit today, and the cylinder is smaller than the one that I took out (by about 1/16th). I guess someone before me decided to bore it out to something bigger than a 500cc???
This is where things get over my head and beyond the tools that I own. I think I will take it to a local machine shop (after its cleaned) and have them hone it and give me an accurate measurement for the piston. I guess I will have to send my top end kit back and try again....
