Ring gaps seem about right for a broken in motor; a piston manufacturer's recommendation I have gives a recommended ring gap of .003" per inch diameter of bore. How did you measure the low compression? did you use a compression tester or just 'feel' it on the starting handle?
Did you check the valve seats and tappet gaps before stripping the motor? Unlike pushrod motors, valve clearances tend to close up with use in sidevalve units leading to poor compression and burnt valve seats if left.
