250r Bore ?

[Ordo]

I have the jug off the 85 getting bored . How can I check the relief on the exhaust bridge when i get it back. I have calipers but not a bore mic. Any help is appreciated.

If you put a nice straight edge from top to bottom of the bore along the exhaust bridge, you can slide a feeler guage under It to check to see If It Is relieved enough.

That's what I thought about doing. But was just a little curious if there was another method of doing it. Thanks!
