My 2002 Yamaha Road Star Midnight has no spark
I have 2002 road star midnight. I lost completely spark on all 4 spark plugs. Before bike was running OK but sometimes on low RPM while idling would skip a firing on a at least one cylinder making spufff like sound. I put new spark plugs, and wiggled a little coil wires. Bike with new spurk plugs would not fire up at all. Checked for spark on all 4 spark plugs - no spark., not even an electrical I lost completely spark on all 4 spark plugs. Before bike was running OK but sometimes on low RPM while idling would skip a firing on a at least one cylinder making spufff like sound. I put new spark plugs, and wiggled a little coil wires. Bike with new spark plugs would not fire up at all. Checked for spark on all 4 spark plugs - no spark., not even an electrical charge going to spark plug. Went back to coils. Each coil (there 2 of them) has 2 spark plug wires and 2 ignition timing signal wires connected to them. I realized that these ignition timing wires contacts are corroded to the point they would not conduct a charge from the distributor to coil. CLEAN ALL THE TIMING WIRES Contacts on the coils. I did that and bike fired up right away and started running much better without sputtering or skipping a cylinder firing. SO DISCONNECT ALL THE COIL WIRES AND BRUSH THE CONTACTS WITH A SMALL METAL WIRE BRUSH.

Some bikes have one or more safety features regarding the clutch and gear box. One feature is a micro-switch at the clutch master/lever, it tells the safety system if the clutch lever is out or in. If the switch fails the safety system will think the lever is out (allowing power to rear wheel) and kill the engine to prevent the bike from lurching forward, potentially causing the bike and rider to go down. The other feature is not as common, it is a similar switch at the side stand. This prevents the rider from starting off with the side stand down. Which can also cause the bike and rider to go down. If that switch fails then the bike will think the side stand is always down and will kill the engine as soon as it put into gear. If you know how to use a multimeter you can test the switch(s) for function and determine if it is failed. Otherwise have it checked by a competent mechanic.
There is also a recall on your bike (and many others with the same gearbox) regarding the power train. A good reason to get you bike in, fix this safety issue and your original issue.

If old gas sat in the carb. for more than a month it starts to dry up. As it drys up it leaves behind a varnish like film that stops up some very small ports and pin holes inside a motorcycle carburetor. It is also very hard to get out. You can try this before you pull the carb. for a full cleaning. Use a product called Seafoam, get as much gas out of the carb.s as you can. use a turkey baster and force the seafoam into your carb. fuel line that you take loose from the fuel tank. Let that set for say 1 or 2 days. then hook up the fueltank with a mix of good gas and seafoam, (not a lot but enough to start it up. Move the cycle outside as the seafoam will make a lot of smoke if it does start up. If that does not clear up the problem you may have to pull the carb. and remove the blows to clean the inside. If you have to do that do not DO NOT MESS with any adjustment screws. Just take the carb. bowl off. Do not mix up any internal parts. It is best to work on a large sheet so if you drop a small part you can find it, you do not want to be missing some tiny spring or screw. Hope this Helps Fix Ya Up..
