A friend of mine has a VTX1800 and he was telling me about having changed the spark plugs on it. I got thinking about it and wondered why it had four of them. I asked him why, but he didn't know exactly how to explain it. How does it work? Two for intake and two for exhaust.:huh: :unsure:

Nope. These should be for better combustion just like the eight spark plugs on my ex zr1100. Supposedly gives you more torque. They fire at the same time to burn the gas more completely or something.
