there is no problem with your bike what i thik it is tht the gas leaks out of the carbeurator tube win it sits to long just take it to a bike shop and the will fix it.

When running it try to use up all the fuel in the tank and when starting give it gas. Not to much or you will flood the engine.

If you have electric start than maybe the battery's dead, or maybe there's old gasoline in the tank. Drain any old gasoline and replace it with new gasoline and recharge the battery. Also, the spark plug might have old gasoline or something in it. Dry off the spark plug and give 'er a go.

 like i told you you have water in your fuel because you left it uncovered for a couple of days when the wheel broke so go get the carb fixed plus your fuel lines are probably clogged remember i used to be a yahmaha tech (i quit my job there 2 weeks ago well i really got fired but still)

 indeed but like i said in the first comment foolow that advice and your good to go your carb you should be able to remove your self if you have the right tools but I would take it to a mechanic that your family knows and trust and have him or her take it out and clean it or take it to a small engine repair place

Are you putting the choke on before you try to start it?

I had a Montessa 250 once that if I didn't choke it to start, I could kick start or push start it for ever and it never would even pop.  Put the choke on and just look at the kick start and it would fire up.

Does it run good when you do get it started?

Answer 11 years ago

Yes, i put the choke on! Yamahas have a reputation of long warm-ups. Even a day after i drove it, i need to apply the choke to start it. it runs OK but not to its full potential. btw mine only has e-start.      :P

ya it sucks. dont even say anything.

Its sounds to me like you need to clean and flush the complete fuel system.
Start at the top, drain the fuel from the tank and dispose of it properly. Don't save it.
Remove the tank, petcock(s) fuel filter and hose(s). Flush the tank with clean water, dry with compressed air and examine the inside for rust and or fuel varnish and clean with a tank cleaner available at an MC or auto parts dealer. Clean the petcocks and replace the hose(s) and the fuel filter.
Remove the bowl from the carburetor and clean out any residue. Replace the gasket and re-assemble.
Re-assemble the fuel system and add fresh fuel.
In the future, drain the tank and fuel system, if you plan on storing the bike for more than a couple of weeks.

.  Make sure the petcock is turned on.
.  Make sure there is fuel in the tank.
.  Make sure the fuel line between tank and carb is clear.
.
.  If all that checks out, time to clean or rebuild the carb.

Could be a sticky throttle plate in the carb. Take the cover off and run the choke back and forth a couple of times and see if anything moves. I used to have a car that would only start if you wedged the throttle plate open (I used the air filter nut). After it started, it was fine. Made driving anywhere on rainy days a big pain in the keister, though.
