And i have another probablem. the last time i ran it it was only 1 wheel drive do you have any idea on the problem.

Whisky, did you drain the carburetor float bowl when you drained the gas? Did you drain the RESERVE portion of your fuel tank (by using the RESERVE position on your petcock)? If not, contaminated fuel in the float bowl or tank reserve could be your problem.

Consider giving the bike some starting fluid, "IV," spray it into the carburetor, spray some into the spark plug hole and replace the spark plug.

What about the kill switch? I'm not joking; been there, done that!

Otherwise, with gas, properly-timed robust spark (I trust you checked to make sure you have spark), and engine compression, your Twolve should start!

About the "one-wheel drive," I can only imgaine a broken axle, since I conceive the wheels spooled together.

I wish you good luck, whisky!

The axle is not broke. I dont no what the problem is. All the power goes to one wheel.

 

whisky, if its on the left side, check to make sure you axle is not broke away from the wheel. Its kinda hard to see, and its real hard to explain, but i've had that problem. And i ended up having to weld my axle to the brake drum or what ever its called. It would be alot easier for me to explain if i was more mechanicly knowlagable. But i hope you can catch my drift.

When you say it wont start, do you mean it wont crank or it just wont fire up? Your choke might be stuck or something. Try roll starting it and see if thats your problem. Hoped i helped a little bit.

How long did you let you bike sit for? Maybe like Tree Farmer said you have bad gas or if it has been sitting for long time the gas in the carb may have dried up leaving a white film inside, this when fresh gas is added makes "floaties" that float around and are famous for pluging up the jets and float bowl. This might not be the problem, just a suggestion, as for the wheel problem, maybe you gears inside of the rearend are wore down or some of the teeth are missing, possible one of the splines on the axle that meet up with the gears is gone bad? Hope I could be some help!! Good luck!!

I agree with whoever said you have a stripped hub . Yamaha bikes are famous for the hub centre nut backing off then the hub works itself loose then strips the spline out of the inside of it. You are either going to get a new hub or weld it to your axle which can make it fun to disassemble in the future. As for the not starting thing , the gas has probably gone stale in your carb .
A lot of people just run their bikes untill they stall , thinking that drained all the fuel.
This is the worse thing you can do because there will still be about 1/2 inch of gas in the bottom of your carb bowl when you drain it with this method . you should either remove the drain screw from the bottom of the carb to drain ALL the gas or do the easy thing and buy a fuel stabilizer from your local shop . This stuff will allow you to store fuel in any machine for up to 2 years without the fuel going stale . But that dosen't fix the problem you have now . You're going to have to remove your carb. disassemble the whole thing (its gonna smell real nice inside too with stale gas) Then soak the whole carb. jets and all in a carb cleaner. I use methyl hydrate which people usually call gas line antifreeze. this works excellent for softening up the stale gas. After soaking it for a couple of hours blow it all out with compressed air and reassemble it the way you took it apart. put it back on the bike and she'll work great. Then go get some fuel stabilizer for next time .
