No, like an fool I didn't. It was snowing outside and I was in a hurry to finish putting it all back together so I could go rip in the snow.

I used the same thickness base gasket at what was originally on the bike when the the PO had the squish mod done. So I figured "it would be the same" now I regret not measuring.

That should be ok, then. I do the same. I machined the head for a .3mm base gasket, and have used the same thickness since, without further measuring.

Now im even beginning to wonder if the previous owner was just telling me he had it done, he was pretty desperate to sell the bike...might have told me anything to get it sold...but who really knows. Might be worth the investment to find out.
