Re: CB360 Cafe Project *Engine Time*
Ok I measure the rings about an inch down from the top of the bore as they will never see the bottom. I also try to measure the bore in at least 3 places, usually the top (after you clean the crap off), about a third down, and then 2/3's down. The rings will wear the bore the most, not the piston skirt, so where they run is where it will be worn out. It can be done with a ring and a feeler gauge. Measure the top with your caliper then take a ring and using a piston push it to those spots. Then get your feeler gauge out and measure the gap on the ring and then add that to the top measurement. It's not dead on but will give you a really good ballpark figure. The highest number is your measurement.
Did you take your caliper to the pins? and the rod ends? Those two spots will wear badly if the engine was ever run low on oil or with gas in the oil.
As far as running what you have, what was the compression like before you took it apart? Did you measure it? If it was where it was supposed to be, (above 160 cold and 170 hot) put the somebitch back together and run it. MAYBE, MAYBE hone the glaze off the cylinders and then re-ring it.
What do the valves look like? Have you done the acetone test to them to see if they are leaking? A well taken care of motor with 10K miles on it should still be good for at least another 15k if not more.
As for finding funny things this was in mine,
Not to mention when I first changed the oil when I got mine, the pick-up screen was clogged with what looked like a hand full of dog hair.
