Are the two inside cylinders firing? If they are, did you "read" the plugs after the bike sat at an idle?

PS...your going to love that bike, once we get it running right!!! A near twin to mine.

You don't metion how much the bike has been ridden recently. Until you have driven it far enough to get it fully warmed up and the choke fully off the plugs won't tell you anything. Does it start and idle OK? From what you say about the plugs it sounds like it developed a problem and was parked.

Lablow,

Welcome to GSR.

Hey another 650.

Lots of folks here willing to help, and most of them fairly knowlodgeable to actaully help har har

You didnt say if it was running or not, or how well it was running.

WHere are you located?

Try a new set of gapped plugs and then see if the outer two are black and wet. If so one of the coils isn't firing.
One coil fires 1&4 and the other fires 2&3.
