Hi I'm new to all this but here it goes. I have a 1986 suzuki intruder 700. It's a bit of a running project but I went out to get fired up for the first time this year and put new gas in did a couple other checks and hit the switch. No surprise it didn't take right off. No big deal though... or so I thought. It did try to fire a couple times so I figured I'd throw a new set of plugs in. Did that and now absolutely no spark even with putting the old plugs back in. Don't know what would cause that. Please help. Also I am simple so simple answers would be appreciated.
