bad fuel smell if bad old fuel can cause backfires and poor performance as well as carb headaches

Should be standard anti-clockwise, 'lefty loosey'. https://www.google.com/search?q=2008+yamaha+c3+scooter%2C+remove+back+wheel ..

Stand the bike on it's centre stand or a track stand to make sure the bike is straight and upright. On the side of the transmission is a small window with a centre line marked as LOW. It might be near the gear shift pedal. This 'Site Glass' should be the colour of the engine Oil. Using a helper GENTLY rock the bike side to side. The colour of the window should not change if the oil level is correct. I you can see a fluid level line when the bike is upright or when you rock it the oil level needs topping up.**NOTE** The entire engine uses Less than One Litre of oil so topping up will only need a tiny amount. There is a Check bolt mounted higher on the engine you can use to check for any over filling.I've attached a link to an owners manual for the Yamaha YZ450F to show you what to look for and how to do it. The basic method is the same on most motorcycles. Look at pages 3-14 and 3-15.https://cdn.yamaha-motor.eu/owner-manuals/Motorcycles/B11-28199-80-%20YZ450F-EN-2016.pdf

Try checking the ignition itself (where your key goes), then ignition coil. also check relays, bad/bare wires, bad ground etc. etc. However, don't just go throwing parts at it hoping one sticks. Get a multi-meter and do it right. Electical issues can be a pain.

They're under the gauge cluster where all your lights are at shows your brake light neutral light high beams Etc that's where your fuses are

Vacuum leak. Check around the intake, check vacuum lines, do a compression test to make sure its not a head gasket. Really lean fuel can do the same thing. Something else to look at if there's no vaccum issues. An example would be a carburetor that's jetted too lean. Fuel injected can have issues too, but not as common. Start with vaccum first though, it's your best bet

it sounds like the recitfier/ regulator needs replaced

I'm assuming it was a new starter motor not a second hand unit. Not all 'new' batteries are fully charged when you buy them so if you have a charger put the battery on charge overnight to make sure it is at it's max. Next turn everything else OFF before you start the bike. Each thing you turn on like the lights takes power away from the battery. features like the lights and fuel pump don't use a lot of battery power but a starter does. With a multimeter set to DC Volts check for power supply to the starter itself and to the Solenoid that triggers the starter motor. You should get somewhere around 12.6 volts. Does the bike start if you 'jump' the solenoid? (a thick INSULATED wire or an INSULATED screwdriver across the large terminals of the solenoid). You could check if the actual engine turns to make sure it isn't seized. First put the bike on it's centre stand NOT the side stand as you will need the rear wheel off the ground to do this. Get a helper to gently lean on the handlebars to keep the rear wheel clear of the ground. With the engine OFF, with the key OUT and the bike in neutral, keep well clear of the chain and rear sprocket (toothed cog). Roll the wheel by hand. It should spin freely with just the sound of the chain quietly clicking and possibly a quiet 'hiss' from the rear brake. Put the bike into gear, 2nd or 3rd if you can. Try to roll the rear wheel by hand. You will get resistance but it should turn. You should get regular spots of resistance (compression stroke) and free rolling (exhaust stroke). Roll the wheel through 4 or 5 full turns to make sure it doesn't lock up part of the way round. Buying a non-runner is always a roll of the dice. Sometimes you inherit someone elses mechanical headaches.

Sounds like the sensor broke apart. I would be taking the side cover to see what bits are floating around! https://www.google.com/search?q=2005+Yamaha+V-Star+1100+Silverado%2C+my+speedometer+stopped+working this is the sensor https://www.google.com/search?q=2005+Yamaha+V-Star+1100+Silverado%2C+speedometer+sensor ..

Question edited from Australian to English. Question moved to Yamaha category. There must be a switch in the gearbox that is closed circuit. The Overdrive light just tells you that you are in 6th gear. I would ignore it or remove the bulb. :>) https://www.google.com/search?q=1998+Yamaha+FZX250+Zeal+overdrive+light ..

If you mean the engine just revs and there is no drive, maybe it has a gear selector issue. The 5th gear is like an overdrive. I would take it to a Yamaha repair shop for advice.

Question edited for clarity, add maker. Question moved to Category. Check out the link. It it backfires through the exhaust the timing is retarded and firing too late. https://www.google.com/search?q=yamaha+yz80+set+ignition+timing ..

order a new one

A batt must read 12.6v for acoil ign...no less. Testit w a multimeter. Twelve volts is actually disharged. Getta new batt if it doesnt hold charge
