Topic: Measuring ring gap 750

[AshimotoK0]

The Honda manual says "When only the ring is to be replaced without boring the cylider wear, the ring gap should be measured at the skirt of the bore"
 
What position is the 'skirt of the bore'

 Also if measuring bore wear with the piston in the bore (with no rings fitted), where do you insert the feeler?

The skirt is the every bottom where there is no wear. Fit the ring inside and slide a piston down against the ring to make sure it is square.

The second part, insert the feeler between the piston and wall of the cylinder. I've never done it, but I would think you need narrower feelers to get an accurate measurement.

Actually you insert the feeler gage between the ends of the ring, in the gap (with the piston out).

That's for measuring ring end-gap, not for measuring piston-to-cylinder clearance.

Ooops, I got it.  Just reading too fast.

I do have a fancy bore gauge (gage) but getting used to using it is new to me so I am 'cross checking'
