[QUOTE="Henry Martini, post: 4530, member: 48"] Hi Stewart, I am running my twin with Pazon ignition. I was using BP6ES but now am using DENSO IRIDIUM IW22 no problems all Iridium plugs have built in resistors so I use a plain no resistor plug cap I did run the Denso's with resistor plug caps but the Pazon ign systenm did not like that.I have used the Pazon system since the Canadian International 5 or more years ago never any problems. I did however find that using the recomended MK2 carb jets and settings the plugs were always very black and needed frequent cleaning or replacement. In the last year I have spent much time on leaning the mixture am now running smaller main jets 4 1/2 slides and It now runs smoother and faster then it ever did the plug colour is now almost right and I get 60 miles to the gallon at a steady 60/70 mph and 48 to the gallon at a steady 80/85 mph I belive it is still running on the rich side of correct. I can't remember the main jet size but if you want I will check it out. The best to all Henry [/QUOTE]
