I've still got a low rev misfire on the front cylinder and wonder if it's a PGM problem

The top end has been recently completed and have about 70 miles running in so far.

New parts fitted;
air filter element
coils
front plug cap

Gibsons have had it on their dyno and say it runs ok through the rest of the range after cleaning out the pilot jets.

Does any one know if a Honda dealer would have test equipment or does anyone have a spare I could try out?
