fantic tom Posted February 12, 2016 Author Report Share Posted February 12, 2016 well im finally getting somewhere, I took spark plug out and earthed it to cyl head and its sparking but not well. its got a new coil so should it spark well with this? what else could cause a poor spark, a duff spark plug? i wouldn't mind the first thing i did was order 2 new spark plugs but the top nipple where ngk lead attaches was different. can i fit the new plug with a different ngk lead end or where do i get the same skinny headed plug from? such a simple problem stopping it running i think, annoying as engine had been rebuilt last year! cheers! tom.

fantic tom Posted February 12, 2016 Author Report Share Posted February 12, 2016 iv ordered a new spark plug cap to match the plugs iv ordered with same part number. ill update when iv tried it. thing is it always starts first kick so it must be summate and nowt.

fantic tom Posted February 12, 2016 Author Report Share Posted February 12, 2016 Is there a resistor built into spark plug cap or in the spark plug? Quote Link to comment Share on other sites More sharing options...
2stroke4stroke Posted February 13, 2016 Report Share Posted February 13, 2016 Just unscrew the nipple from the top of the plug. It could be that there is not a brilliant connection between plug cap and HT lead. Cut it back slightly then screw the cap back on. Is there a screwed connection at the coil end? I don't recall resistor plugs specified for Fantic so you want neither resistor. I have known bikes with a poor looking spark that ran well for years.
