Default Spark plugs
I have a 1989 Harley fxsts springer with a 1340 cc evo motor. Is there a multi electrode spark plug made for this motor? Currently running champion RN12YC plugs and am having trouble with gas fouling with the S & S super E carb. Have already changed the jets to smallest ones available. Would a Yost power tube also help?

The Champion plugs are very prone to fouling, Go to your local auto parts store and get a pair of NGK VR4's and the problem will go away.. Worked on my 1991 EVO with a super E carb

I have been using the Yost Power Tube for over 4years now... I am very impressed with it. Take a look at Pulstar Pulse Plugs. They have 30-day money back guarantee to out perform your current plugs & a 2-year warranty.
