Have you tried the gap test? It should be able to jump a 5MM gap. What color is the spark? It should be blue. Does that cylinder fire properly once fully warmed up? My guess is that you're issue is fuel rather than spark. Pilot jet is dirty on the #1 carb. It let's enough fuel in for it to fire occasionally. Sent via BlackBerry by AT&T

I'm a proud owner of an 82 650 NH. I just purchased it about a month ago and I am in the process of getting it running smoothly. The previous owner had stored it for 10 years. I am having a problem with weak spark on cylinder #1. I have checked both coils and tested them and both are fine. Wires are all good. I am getting power to all the connections and still weak spark. The bike will run but cylinder #1's exhaust runs cold and the exhaust smells very rich like its not firing completely. Its got new plugs a full battery and new air filter......Any advice would be greatly appreciated. I'm stumped....
