Very likely the plug wires. Idles perfect but rev it up and they throw sparks in headers and places that aren't easy to see.
I'd have a look under the dist. cap too but a problem in there usually causes crossfires and backfires.
It doesnt back fire or anything like that. So I think I will swap one wire out at a time and see whcih one of those buggers are the culprite... Thanx RedFish
