I have a buddy of mine that wants me to tune his bike up for him. He wants to put E3 spark plugs in it. It looks like there E3.36 will work in the 1250 motor but I have never been around these plugs. I have always ran NGK in all my gas motors. Looking for any info on the E3 plugs I can get. Anything you guys have seen or heard would be great. Thank ahead of time.
