IF, and I doubt that, you can FEEL a difference in power between the two cylinders, you have a bigger problem, than RC valve adjustment.
You can't judge from the smoke. I never found out why, but the NSRs have a tendency to smoke more from the lower cylinder at start up and some minutes after.
PS: There is a bushing in the cylinder for the RC valve and this can wear. I had a cylinder where the bushing was missing. I didn't check if the piston could touch the valve though.
