did you replace it with a oem switch?There is on some bikes a anti theft device built into the key switch.If you replaced it with a after market switch thats your problem.There is a resister built in the oem switch .You would need to soldier in a 100 ohm resister to make the aftermarket switch work.My advice is to put in the oem key switch

Check the battery.Is it charged?Also does the neutral light go on? If not check the neutral switch. The neutral switch is behind the engine case near the rear shock and has one wire. Make sure the bike is in neutral or on stands. Remove the one wire and put it to earth/chassis/ground (somewhere metal on the bike). The neutral light should come on and you should be able to start the bike if that was the problem.

possible corrosion in the indicator switch. not hard to remove, just tedious.

You can fail emissions on a bike in arizona ? Wow i thought california was bad....anyhoo let's get to your concerns....All those srews should be very close to the same setting....rule of thumb is start at 1and1/2 turns out on each screw, almost any gasoline engine will run at these setting then you can fine tune from there.....no wonder you had bad idling problems...Good luck to you friend....Tim

Check the fuses

It sounds like a sensor not working good and did you check all the connectors from the front to the back of the bike to make sure that is no debris in there plus get an ohm tester and test all you wiring if possible including coils sensor switch etc.

Normally I get the ground from the engine case or main frame not subframe or swingarm

Most likely a blown head gasket. Exhaust gas is blowing past the gasket and into the cooling system. It will pressurise the cooling system and push the coolant into overflow bottle. You might notice that after riding the bike for a while and then leaving it to stand for a few minutes, it will push coolant back into the cylinder and you will get a big puff of steam out exhaust when you start it. Best way to check is to do a compression test. Need to remove spark plugs and and screw a compression tester into the hole. Crank the starter and you will see the gauge go up in 3 or 4 strokes. Should be about 224 psi for a new stock motor. Repeat test for remaining 3 cylinders. Pressure should be 90% of that figure (201) and should not be more than 10% different from highest to lowest. Probably find one cylinder is really low.

Yes it might have shorts inside the coil.

Bring it to a certified Yamaha mechanic

Disconnect the wire connections and OHM them out to ground. If you have a short to ground the wires will melt.

re check timing and valve clearances.

it's because you didn't accept jesus

altanater

One opens the intake vales and the other opens the exhaust valves. they are made so you cannot install them in reverse.

1,000,000,,0000,0,,0,,0 PSI. They actually wear little superman symbols on them.

It needs the carbs cleaned and sync'd. don't risk blowing it up.
