Leaving it a bit late I know. But my 1100 hyper is going on the dyno on Thursday now it’s all run in after engine rebuild last year. At the moment it’s got NGK iridium plugs in. It runs fine but do you reckon I should stick a fresh set of non iridium ones in or do you think if it ain’t broke?? I’ve heard tuners don’t like iridium plugs? Something about the spark being smaller. Im obviously Going to have to source a set a bit lively if I’m going to change them.
