CB500/550 / Re: NGK plugs for 500
« on: Today at 10:07:59 PM »Ted, if you can find any D7EV are the dogs doodads for the 500, it should have had newish D7EA in it when you got it, D7ES is the original and not available the A is same as S according to NGK. You should not be using the R typeSo a resistor spark plug when you have resistor plug caps does this cause a problem somehow ?
