Do you have both resistor caps and plugs, if so that would most likely be the problem.
Jon - stupid question but check your main jets. I had an almost identical issue on a 750 recently. Previous owner had drilled out the main jets to prob 150-160 (should have been running 120's) and it was the last thing I thought to check (the mains were stamped 120). May be a red herring but worth looking at when you have the carbs off...
Be careful, its going to be very difficult if not impossible to avoid getting swarfe in the cylinder when fitting any kind of insert. Will need to be vacuumed out somehow.....

At the same time he did the tapping he was blowing air into the head via the exhaust port!
