96 bandit, wont start,will turn over but not fire up, have changed plugs, drained carbies, checked for spark, still not firing up, any ideas?

If you tried to start the engine for any length of time, the plug would be damp and smell of petrol because fuel was being drawn into the combustion chamber. Without spark to ingnite the mixture, it would cause the plug to become damp. I am assuming you fitted the correct spark plug and that it is gapped correctly.

I don't mean this to sound foolish, but I would suggest you make certain the emergency kill switch has not been accidentally switched off. Also, if you have a sidestand safety interlock that prevents the engine being started while the side stand is down, flip up the sidestand and try again to start it.

Additionally, to make sure the plug wire is securely fitted to the plug. It is possible that the inside of the plug wire cap has gathered moisture and may need to be wiped dry.

If none of the above suggestions solve the problem, remove the plug then reconnect it to the plug wire and hold it near the cylinder - but not near the plug hole in the cylinder head (fuel vapors) - while pressing the starter . You should see an obvious spark. No spark likely means the coil is faulty.

Clean the air filter and, if you have one, remove the water trap bowl on the fuel petcock and clean it. How good is the battery? Install new STOCK plugs. Bear in mind it may be time for carb kits. Other than your cleaning the carbs, the carb kits and balancing and synchronizing of the carbs are best left for the shop to do.

Check the exhaust pipes. If there is a restriction in the burned gases exiting the tailpipe then the bike will not run right, will loose power and even die if too much back pressure builds up. Disconnect the exhaust system and tick off the neighbors with a quick ride around the block without a muffler. If the engine still dies then exhaust is not likely to be the problem.

Check the compression on all cylinders. Depending on the compression, the bike may be ready for a valve job. If you pull the head for the valve job then you might as well consider re-boring the cylinders and install new pistons and rings. Bear in mind, doing a valve job and / or pistons is not recommended for the novice. The good part is that when the work is finished you will effectively have a new engine.

Do you have fresh gas in the bike? Try changing the plugs with new ones and check for spark. You can do this by putting the new plugs on the plug wire and grounding it to the head on the engine crank the motor over you should see a bright blue spark. Check one plug at a time. No spark check the ignition wires and coils. As for the oily plugs it could be they are just fouled caused by either flooding the motor while trying to start, bad plugs, week coils, bad gas, poorly adjusted carb's. I would start with the plugs and work my way back to the carbs. Still fouling the plugs after all that start checking the engine, ie compression check ect.

Check the valve adjustment. If a valve is standing open just a little, the compression will be too low to start the engine. Check fuel delivery by dribbling a little gasoline into the carb and try starting the bike. If it starts and runs for a second or two, you're not getting fuel into the cylinders. Check you carb again.
