Bike will start , but only runs for about 3-5 seconds with the choke wide open. any suggestions?

"Crank" and "turn over" mean exactly the same thing. I think you mean it won't "fire". How did your choke cable break on the highway? You shouldn't have been pulling (closing) the choke at that point - does that ride have other issues?

It might be flooded now - try letting it sit for several hours, then try starting with the throttle WIDE OPEN and no choke - that helps clear extra gas out of the cylinders.

You might also need to pull the spark plugs and dry them out thoroughly.

check the air filter or try running it with the lid off the airbox

I would suggest a new plug and fresh gas and oil mix.push the primer bulb 8-10 times and turn choke to full.pull cord about 4 or 5 times until it starts.if it don,t stay running turn choke to half and pull cord until starts should stay running.let run for about 10 seconds then turn off choke.Almost forgot that during this whole process you hold throttle wide open.

The pilot should be open. This is to say that if you look through it at a light you should be able to see through it.
I suggest blowing it out with compressed air as well as the hole it fits in. While your at it give all the jets a blow out.
once you've put it back together I also suggest you fit an in-line fuel filter.
This will help to keep the dirt out and save you having ths same problem again
Hope this helps

clean carburator it will run fine after

Sounds like your flooding it out with the choke out. Try the next time you go to start the bike when it's cold with the choke out and when it starts push the choke all the way in and keep it running with the throtle. If it runs better after doing this then your flooding it on start up. Use 1/2 choke to start cold and see what it does. Good Luck

sounds like bad fuel try adding some fuel stabilizer.

Gasoline- thank you. Warm up is not an issue like diesel is. Sounds like the choke is is either wide open or over choking. With the engine cold, remove the air cleaner and note where the plate is at the opening of the carb. If it is wide open then without touching anything else and engine not running, step down on the gas pedal and see if the choke plate reset itself to restricter the carb inlet. If it didn't, then take some WD 40 and spray the linkages and the rod ends holdin the choke plate.By hand work the plate and linkage holding the gas open at the carb. Then set the plate to wide open and do the gas pedal thing agan to see if choke sets itself back to restricting the carb intake. If it does, start the engine and as the engine warms upm the choke plate should start opening on its own and you are off and running. Roitine question. Is your air cleaner clean? If the choke plate needs adjusting. get back to me. K? Good luck Remember to press the gas pedal down once before cranking. That sets the choke for cold start. Hope this helped you Good luck Note, the WD40 won't hurt anything but avoid spraying with engine running or when engine is hot..

Try better quality gas. I had the same problem. Ethanol too high in lower grade gas. Buy better grade or ethanol free. Mine works fine with better gas.

you need to check your choke prob not a choike issue just you have it open or its stuck but it sounds like a easy fix
