hmm. I did remove the pilot jet, cleaned it out with compressed air, carb cleaner, and fishing line.

I tightened it down pretty good, as that is the position that I found it in. Do you really think that could be what is causing this? I really don't want to rip the carbs out again.

Also, to clear the gas in the carbs, do you hold throttle open with ignition key on or off?

Thanks for the help

 

If we are talking about the same jet. The main jet, which is inside the float bowl, gets tightened all the way down. The pilot jet, which is located outside the float bowl towards the front of the carb, gets "set", not all the way down. If you did in fact tighten the pilot jet all the way down, that would explain why its not starting. The pilot jet controls the fueling from idle to about 1/8 throttle input. At that point, the main jet begins to take over. So, if you have the pilot jet completely shut, fuel cannot get into the engine.

As for the wide open start. You do this while trying to start the bike. If the bike is flooded, wide open throttle without the engine running introduces a lot more air than fuel, and can clear out the combustion chamber of a flooded engine. It basically makes the extremely rich "flooded" condition leaner so its able to ignite. It sometimes will work on flooded engines. But it can also have the opposite effect if it doesn't start. You have now introduced a lot more gas into the combustion chamber if it doesn't start.

 

Run the fuel from tank straight to carbs. Bypass pump. If it fires you know you need a pump.

 

u should drain the gas from the 4 bowl carbs in the first place before u start up , try to use air gap plugs NGK iridium.

I think that is probably my problem. I plan on tearing it apart again tonight. Any idea how far out I should leave that jet? 2 turns?

Thanks again

 

Well, after tearing her apart again, I realized that I was thinking of something else. The "Pilot screws" that need to be a few turns open are all good. I was thinking you were talking about the two jets that are inside the bowl. Both of those are tightened all the way down and the screw is about 2.5 turns out.

I am stumped again.

There was gas in the bowls, so it has to be something with the carb, right?

 

Anyone have any other ideas?

 

Pull out the battery from the bike then use the car battery (off engine) press and hold the start button in 6 sec. and if it is working turn it off the motor asap. unplug the car battery and Put it back the bike battery , if the bike still not working then u need to clean up the combustion chamber.
