Motion pro sells a spark checking tool but you can do the screw driver in the plug boot trick. If a spark can jump a 7MM gap and is bright blue you coil/wire is fine. I personally think its got gummed up carbs. Also be sure you know what direction is correct for the choke lever, Honda has changed that a couple of times over the years. A proper running bike should start with full choke, NO throttle, hit the button. If its cold it will lope a bit for a couple minutes and then the revs will shoot up. Until that happens if you touch the throttle it will probably die. The next time you get it to start feel the pipes and make sure they all get hot evenly, if not then you know what carb is REALLY dirty. When I first got mine it would only start on 3 cylinders but would eventually run good once warmed up, a thorough carb cleaning fixed it. Sent via BlackBerry by AT&T

I will try checking all connections. I may just say a little prayer that the problem is in a connection. ( because I just checked the price of a coil ) Yikes !!! I would very much like to know how to check a coil when you come upon that information also. thanks again Fred ________________________________ From: LBOCEAN <[email protected]> To: Nighthawk Motorcycle Lovers! <[email protected]> Sent: Sunday, January 8, 2012 9:36 AM Subject: [Nighthawk Lovers] Re: 1986 Nighthawk 450 Not sure what Grahms awnser is to his solution, but I would check a couple of things... 1) Reseat all plug wires to insure good connection. You may want to also check the connection at the coil itself. 2) I would also check the coils themselves for good output. There are seeral ways to do this, which can be found on the net. (I'm just digging my Nighthawk out from storage, manuals, notes, when I locate can offer more on this). Ques., When were the carbs last cleaned/adjusted?
