I own a 02 1200s. The problem is it was left running in idle for approx. 20 mins. Now the pipes are discolored and I can't seem to operate the bike. It will start and run. By the way I immediately changed the oil. However, the bike will start and run sounds a little different than before but no knocking. The green neutral light is not working properly, flicks on and off. As soon as I drop the choke and try to roll the throttle the bike dies. Also, green light will be lit and go out. I'll pull the clutch in and slip into ist, then back into neutral. no light? ANy ideas?

I don't know if anything got hot enough to melt some sensors, wiring or switches....

Maybe the plugs fouled? (Might have something to do with running problems.)

I kind of doubt leaving a bike idling 20 minutes would do any major damage, unless it was hot to start with, and it was a pretty hot day.
Was there any 'smell' to the bike when you shut it off?
I haven't heard of anyone 'cooking' one, and have no real mechanical basis for my guesses.....

I didn't shut it off. It stopped running when I returned. Smelled burnt oil. Did not check the plugs. However bike was extremely hot.

I can start it up, the neutral light will go off after about 15-30 secs. I have to drop the stand, pull it up and pull in the clutch to start. No green light will ever come back on unless I leave it off for a bit.

Hang on, somebody may have a better answer in a bit.
With the intermittant lights....I'm thinking something electrical got melted, but....that may be the least of your problems.
I'm just guessing. I've left mine idle 10-15 minutes or so when I started it cold, but.....???

ok.. i have to ask, why did you leave it idling for 20 minutes?

Have no idea what it could have messed up though...

I would hope that a bike could be left running for 20 minutes, at idle, without any issues, unless of course it didn't have any oil in it!

I think your light issue has nothing to do with this. Check the connection of the bulb. Sometimes your tail light can be intermittent too!

Well, I left it idling while I went inside, got caught up in my children's argument. Yes it did have oil in it. You are correct, because my taillight from time to time is a little touchy. Just seems strange that I never had a problem with the indicator light prior to this incident. I will pull the plugs tomorrow and check them as well. I know the bike got HOT because my pipes are now purple/blue. I'm a little concerned that I may have damaged internal parts due to the extreme heat. Once I pull the plugs and check, I'll try to go for a ride if I can give it gas without the bike dying.

Anyone know how to check the neutral switch? Where is the sensor located?

Did it go from a tan color to a deep purple/blue color??????

Are you currently running an aftermarket pipe without rejetted carbs???

Your plugs will tell you quite a bit. If they are snow white and blistered looking, maybe you did overheat her. Replace the plugs while you are at it too.

Sorry about your troubles.

Stock everything. Also, if my indicator bulb was bad, I should be able to start it while stand is down and I'm in neutral. Pipes went from a lite tan to the discoloration.

i dunno.. if there is not any airflow, i think it could cause problems..

It's an 2002 model... how many miles are on the bike now?? when was the last time you checked the valve clearances? Are you observing any smoke out the tail pipe when shes running at idle? The fact that it won't take any gas almost seems like maybe a vacume leak developed after the heat. None of the wire harnesses come close to the engine, except for the spark plug wires. You might want to pull the tank and check the wire harness/plastic connectors that run along the top side of the frame, just under the tank. Also check the plug wires, coils, and all vacume connections (pair valve t-connector, fuel tank petcock, and at carbs). Look for any sign of melted plastic or discoloration. Double check tightness of all fittings.

After that, you may want to get the compression checked and do a leak-down test. I hope you don't have to go there.

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.
