Anyone use Iridium plugs? Anyone know if they foul less than standard plugs?
My fuel injected R1 is sluggish on startup and it seems like the plugs are fouling after cooling off or sitting overnight. My first thought is to change the plugs and see if there's an improvement. The bike has about 5000 miles on it. Anyone know if this is typical behavior for Yamaha products?
My Honda never did such strange things...
