I have pulled my crankcase apart on my 1978 CB 400 T II mainly just to check things out and get it cleaned up. It has been sitting for about 8 years. It ran pretty good at that time, had some overheating issues. Odometer says about 10,000 miles on the bike which I believe to be true. There is a bit of carbon build up on the top of the pistons but everything else looks in pretty good shape. My question is whether I should replace my rings. I am going to remove them and clean them up, and i will measure them to make sure they are still in tolerance and replace them if they aren't. But if they are in tolerance (I am assuming they are due to the low miles and low visual wear) should I replace them anyway since I am in there? Also, if I don't replace the rings should I still hone the cylinders or do I assume they will still be well seated?
