If you break it in correctly, it shouldn't have a problem running it, but it will take some time to get that first tank thru. The P/S set for the NSR was so tight it would not turn over with my box. It was so bad the starter box belt actually stripped. After replacing the belt and getting a heat gun, I got it to turn. My RB was even worse. For the first 8 tanks, I still needed a screwdriver to unstick the flywheel.
Well, I was told not to use the screwdriver technique, because it can scratch the piston or something. It was recommended to just use the heat gun, but eventually I had to use the screwdriver because the flywheel would not budge!!
