The bike ran well, didn't pull as hard to the rev limiter so I short shifted it to make use of the mid range torque. I did put a bigger radiator on it, I can not tell what it is off of as I found it at a swap meet. Ran a temp guage on it as well, coolant temp stayed right at 180 degrees.
So in comparison to other bikes? I beat every KTM390 (4 on the grid) every ninja 300 (3), one yamaha R3, Ninja 250"s aren't a challenge,1 Aprillia 250 cup, bike, 1 electric bike, 1 Hawk, Raced up into the lightweight field and waxed an air cooled Buell and several ametuers on SV650's.

nice to hear you're having it running again...
you did the right figure about squish, will be safe and sound that way...
the lack of appetite for top revving is mostly because you're usinh the 250 head with the small intake valves and the cam duration... switching to wilder cams and bigger intake valves or a whole 300 head will make it unbeatable...
but keep it that way for a while, no need to take it apart now that you got it right...
