All the sudden my bike has been acting up. It starts right up but then dies almost immediately. I have new battery and new spark plugs. It could have possibly had bad gas in it but I did drain the tank and put new gas in it. Any help would be appreciated. Thanks

 

More info would help. How many miles, what kinds of mods if any, any work done lately? Did it just happen after the new battery was installed?
Without any more to go by, start with the simple stuff.
Since the battery is new, check the terminals and ground connections. You could have a pinhole in the fuel tank line or a clogged fuel filter.

 

8500 miles. No mods. The bike got pretty wet during a rain. I recently siphoned gas out of tank because I thought maybe water is gas. I took it to get gas and everything was fine. As soon as I pulled out it started bogging down and no acceleration. Then wouldn't start . Now with new battery it starts immediately but dies immediately.

 

With the rain involved I would look at drying out plugs starting at the ECM and plugs to the coil. Also check the plug at the crank position sensor on the left front of the engine close to the end of the oil filter.

 

Any codes?

 

No codes. It's pissing me off.

 

Nothing even happens when I hit the throttle either.

 

What does the air filter look like? Tank vent plugged?

 

Everything was fine all summer. This is all sudden. Air filter is a little dirty. But this is all out of the blue

 

Check loose battery cables. Also check ground connection behind battery box against rear fender. Consider loosening and retighten.
