Happy ending.. I love that!
In my case I hade a slugish last ride in late sumer, I thoght I was out of fuel, put it on reserv and filled the tank on nearest gas station.

It still work slugish, but I did manage to get home.

After a month, I tryed to start it, there was no ignition at all, the battery was caput/broken.

Soo I bout me a new battery, and it started right on!

2009 S40 938miles. Florida Panhandle. Bought it 5 days ago and drained the tank. Cleaned the carb. Shot engine fog in the plug and valve hole. Got it to crank with starting fluid but thats it. Got the Raptor on order but trying to crank it with the old battery assisted by my charger. Just now got back with a brand new battery (it's on charge) hoping that in the morning it will fire and run. The plug looks good but dry.

Do you mean that you got it to fire with starting fluid? If it kicked with starting fluid, and the plug is dry, you have a fuel delivery problem. Hopefully the petcock does the job for you. When you sag you cleaned the carb, what does that mean?

Posts: 66	Re: Engine does not start Reply #20 - 12/09/20 at 21:08:49 I pullled the carb and carefully cleaned it with instructions from this site. I may have missed something cause it does not seem to get any gas. The oem petcock will flow set on primary but not on any other setting. It runs on starter spray for about 20 sparks. Hoping the new battery will cure it in the morning.

The new petcock has three positions; OFF - ON - RES. You will have flow to the carb on either ON or RES. The vacuum petcock that you currently have will only flow fuel in PRI without the engine turning over. Once there is engine vacuum (during the intake stroke) fuel flows in the RUN position.

If your OEM petcock flows fuel in the PRI position but not in the RUN position, it is probably working correctly. However, its only a matter of time before it will fail so it is worth the effort to make the change.

Between the new petcock and the new battery, you should have a running motorcycle in short order.

The petcock is working properly. With the engine not running, it should only flow fuel in the PRI position.
Do the following to verify fuel is getting into the carburetor.
Turn petcock to ON.
Open carburetor drain screw and a few ounces of fuel should drain out.
After fuel stops draining, turn petcock to PRI. Fuel should start draining again.

If the petcock is acting correctly, but the carb bowl is dry, then the float height needs to be adjusted. Its possible that the float pin assembly wasn't put together correctly and the float isn't moving in a position to open the needle valve - allowing fuel into the carb.

You can try hitting the float bowl with the big end of a screwdriver to see if it clears the problem...but I'd rather inspect it to make sure it's OK.

UPDATE
2009 S40 Calif model 938 original miles. I've had it 7 days now and worked on it every day with the advice of this forum.
Washed the old gas out of the tank.
Pulled the carb and cleaned it really good with help from this forum.
Charged up the old battery, Pulled plug and timing door and sprayed engine fog.
Put fresh gas in and tried to crank it. It would only run mabey 3 seconds on starting fluid.
Went and got a new agm battery and put it in. No better.
The Raptor valve came in today and I got it installed and plugged the wire wrapped vent hose.
Tried to crank it...no....no...some fireing...some firing and finally it cranked and stayed cranked. Ran like crap and still does. Constant backfires, gotta keep high throttle idle or goes dead. Ran down the road for bout 1/4 mile. Clutch good, brakes good, lights work good. But, this thing runs like a grouchy old man thats constipated.
After getting it hot..drained the black stuff out and put in a new filter and some Rotella. Swear it ran a little better but still grouchy.

Don’t clean the jets, replace them. While you are waiting for the new jets to arrive, use carb cleaner and compressed air in all of the orifices. Let the carb cleaner sit in the carb for some time (30 minutes or so) before hitting them directly with compressed air.

Probably missed something like drilling out the air screw? With only 938 miles on it....it was gummed up but cleaned out quite well. Used plenty of carb cleaner and the one gallon soak cleaner. Man....I hate having to re pull and clean that carb again.

Did you accidentally reverse the main jet and the pilot jet? Is the diaphragm in the correct orientation? If the engine is running poorly, it’s worth the effort of giving the carb a proper set up.
