Fellas -
Just got done rebuilding my top end, thanks to everyone who provided invaluable advice along the way. here's what was done.
-new cam chain
-new cam bearings
-smoothed out intake and exhaust ports
-lapped valves
-new 1mm over piston and rings + bore and hone
-new elephant foot adjusters
-valves guides, gaskets, etc.. other bits and bobs worth doing
My question is concerning what I can expect as far as compression goes. I know there's a million opinions out there on the right and wrong way to break in a fresh rebuild, so far I've been sticking to the leo method of rolling on and off, but I only got it started today and have probably only put a few miles on it. Anyway...my compression reads ~130 in both cylinders - is this a good starting point? Just want to see if I'm still on the right track, this has been my first rebuild and I'm just stoked it started and runs as well as it does.
