3644 miles. No smoke at idle. I don't know what's wrong. I never checked the clearances. Thanks for the info. I'll let all know what I see tomorrow.

I was thinking maybe a tight exhaust valve that got real hot. This however seems unlikey with that few miles on your bike. A few guys have reported tight valves at the 600 mile check but not many. You would also be seeing some smoking too, if that was the case.

Let us know what you find under the tank!

FWIW, the neutral switch is behind the engine sprocket cover. You'll see a wire dropping down the top through a rubber grommet. From the Haynes manual, you'll want to take off the shift linkage arm, making sure you mark the position on the spline. Then pop off the cover. what little details they have are on page 8-18. The manual is online, with instructions on how to access it in the Members Only forum.

THis may be a red herring, but I've had electrical sensors and wiring melt and short out on big diesel engines when you've had an unrelated heat problem. Since the neutral light is acting up, it's kind of logical to check the neutral switch after you've checked the bulb, and socket.
I'm not sure it's in a place that would have excessive heat due to the long idle, though.

JUst an update, I pulled the tank and checked the plugs, which were not foulded but rather whiteish. Changed the plugs with 4 new ones, Did not see any melted plastics however I did not spend much time looking. I had to go to work. Going hunting this morning and will work on bike this evening. I'll keep all update as I find more. Thanks for everyones help to this point. It has given me somewhere to start.

just an update, I pulled the tank, replaced the plugs, lubed the choke, cleaned the carbs and replaced the neutral switch, new gass, oil, and filters. Runs great now. Anyone have any ideas on cleaning the discoloration off the pipes? I tried chrome cleaner and MOthers polish. Thanks for all the advise and suggestions!

and I owe ya'll a few beers!!!

Mothers will do it if you work on it a while.

If you don't mind dulling the finish slightly, use a Scotch Brite pad. Fine or Extra Fine (if you can find one). You can then carry on with Extra Fine steel wool, and then polish the whole thing with a metal polish like Solvol Autosol and a buffing pad on a drill or similar. It should remove the colour, but it is a lot of work.

if you have or can get a polishing wheel, have a go at it with that! not sure how well it will work out for you, you have heated the metal to it's discolor temp, they may never come back! if you want to try and hide it and give your bike a bit of a race look you can go header wrap, or you can pull it off and send it to be coated, or paint them yourself! the coating or the wrap may help you run a bit cooler, they are suposed to hold the heat inside the pipe, keeping the air flowing over the motor cooler! i think the header wrap would keep more heat in in than the coating!
