Damn firebolt only running on one cylinder

[tomahawk1976]

Any ideas? Sat all winter....I drained the gas last week, changed the plugs and it ran okay for its first outing.....now its only hitting on one cylinder and I'm kinda stumped

Have you done anything at all to check it? or would you like us to totally guess?

Check spark. Check spark plug (again).

Check fuel injector

It all can be done manually or VERY easily using ECMDroid on an android device. Instructions are on Buelltooth.com.

Yes I agree with cooter check plugs, and make sure plug wires are on tight.

Same thing happened to me a few years back. Had one bad plug wire.

You can save some time and trouble by just replacing your spark plugs with new NGK Iridium plugs:

Hopefully he got the plugs changed since May!

Worst case scenario you have a 601.5cc bike.
