Take some Dielectric grease and place it on the spark plugs and also in the plug boots. It could be as simple as a little moisture getting in there and creating a more current friendly path.

Will the map sensor cause the motor cycle to miss ?


Hi Anonymous and the usual suspects are:
1. Faulty wire connector corroded, broken, or loose pins/sockets.
2. Poor fuel mileage.
3. A slight change in exhaust sound and heavy fuel smell.
4. Spark plug electrodes black or sooty.
5. Loose or missing sensor o-ring
6. Check engine light comes on or flashes.
7. Overall poor engine performance; rough idling, stalling, surging, hesitation on acceleration, etc.
There is no video for testing a Harley Davidson Map Sensor, but there is one for a car. All map sensors work the same way no matter what type of vehicle the sensor is located. They all have three wires, on a Harley red is power, black is ground and violet with a white stripe is the signal/data wire. For more information about your issue, please visit the websites below, and for specific information or questions, please feel free to contact me at xlch@mail.com. Good luck and have a nice day.

Honda sabre


I have an 04 Honda Sabre 1100 that does the same thing. If the rain is steady, it will actually die. After you come to a stop, it will start right away and run ok for a little while until you get up to speed in the rain and will die again. Very frustrating. Can't see any shorting when viewing in dark conditions. Bike shop also couldn't figure anything out. Any ideas?
If I figure anything out, I'll repost what worked for me.

93 1200 evo, rough idle, stalling, back firing while coming to stops (using the bikes motor to slow down). power knocks when starting from a complete stop


Sounds like a combination of things. First, are you using high octane fuel? If not, try a couple of tank fulls of that. You mentioned "Power Knocks" when starting off from a complete stop. This is typical of detonation due to low quality fuel.

As for the backfiring and stalling. The engine should idle at about 1000 RPM or so. If it's idled lower thant this, stalling is a possiblity not to mention poor oil of the bottom end. The backfiring could be caused by an air leak into the exhaust system. The mixture in your exhaust system should be overly rich for combustion when you backing down using the engine. If the system is sucking air in at a joint sometwhere, it leans the mixture into a combustable mixture and it ignites causing the back fire. If you've removed the "anti-tamper plug" giving you access to the idle mixture screw, back it out about a half turn and see if that helps.

Good Luck
Steve

Bad engin miss in the rain.


grab a can of WD40 and spray all the wiring you can get to... it repels water. if you want to troubleshoot it with the spray that's possible too. when it's doing that again... start spraying different areas of the electrical system... when it starts idling properly you have found the problem.
i'd start with the spark plug wires and coil

Miss fire, poor running after about 8 miles?


Make sure your vent in the gas tank is not stop up.Make sure your fuel punp is putting out the right amount of fuel .You can check the vent by taking off gas cap But make sure you only have about half tank of gas.When it stard to dothat; put your choke on If it run better you know it in the gas.My vt1100 did that with me and come to find out it was in the carb.But you need to check these thing befor you go to carb along with checking your gas filter.Hope this help you
