Question about Yamaha Motorcycles
My motorcycle will not start in the mornings? However, after i get home from work it starts right up. I am a new rider and this is a previously owned bike, so any suggestions will help.
If everything is in good working order many newcomers to their bikes make a mistake when starting them cold they tend to open the throttle when the motor needs a richer mixture to run and start, now here is the secret lol full choke and do not touch the throttle do not open it when cold cranking the bike,once it starts then as it warms up ease off the choke then your good to go.

Try putting in new, stock spark plugs. Check and possibly replace the air filter. Charge the battery. Get the bike running then check the battery voltage at 2000 rpm. It should show 14volts or more. If not, get the charging system checked. Get a can of starting spray (for future problems).
Get the compression checked. Your bike is 21 years old and I will bet that the valves are needing to be reseated. Check the valve clearances with a cold engine and reset valve clearances as needed. Check the area where the head contacts th cylinder. Any mist of an oil stain? Tighten the head or replace the head gasket. If replacing the gasket, now is the time to have the shop lap re-seat the valves. Have them sync and balance the carbs as well. Your bike will now have its' manners back and show you the dedication it should.

you have a problem with the starter not turning the engine. so we probily not sending a signal to the starter.
you realy confused me when you started talking about gas and choke?
if the engine doesnt turn over none of this even matters.
these new bikes have many safety features .
you have a sensor for netural and you have a sensor for your kickstand and a sensor for your clutch
and all of these have to be workinf right for your engine to turn over.
so with your kickstand up and the bike in netural and the clutch lever pulled in
it should turn over and start.
when it doesnt you need to check your wiring to the switches one might have come loose.
or could be a bad switch.
let us know what you find

Be sure there is a voltage regulator/rectifier in your system.
Its a little aluminium block with small cooling fins, and should be fixed with contact on the chassis.
You can take every regulator, even from a moped for a simple electric circuit.
You just have to know if your bike was a 6V or a 12V one
Otherwise, you can easily make a regulator by yourself, a diode bridge, and a 12V regulator from your local electronics shop.

Shoot WD40 into each cylinder to get them wet.
Change gearbox oil and oil filter. Use 10w40 motor oil in the gear box. Don't use any synthetic oils, oil marked "EC", or oil with "special" additives. Stick with the major brands; Pennzoil, Quaker State, Mobil or Shell. How bad is the rust inside the gas tank? I would consider a liquid tank liner if rusted. Google “ kreem fuel tank liner “ or go to www.http://www.4secondsflat.com/Fuel_Tank_Sealer.html

Look around the accelerator cable for like a little twisty knob thing that controls the throttle and turn it up a little bit. Basically opens the cabs up and lets a lil more fuel in making the rpm a lil higher and should prevent it from stalling. As for the hard to start problem, Try usung the choke a bit and if that fails give it some gass(if the throttle has been opend and closes when off it may be flooded or try replacing the starter motor and battery.
