So long story short i bought my buell xb12s last year and had a ton of issues trying to get it running. after a ton of fixes the main thing that was bad was the intake gaskets i fixed them and the bike ran great. after parking it for the winter i didnt do anything to preserve it and when i came back to it a month ago or so it wouldnt run ive been trying to figure out what the issue is. when i try to start it the only way to get it to start is by giving it gas well holding the starter when it does start i cant keep it running since it either idles for a second or if i give it throttle it will try to run but then die out after a second or two. i pulled the plugs and they looked bad so i replaced them well replacing them i found the wire from the coil to rear plug was very loose on the coil so i tightened that but it hasnt really fixed anything and im kinda stumped. I got it to run for a minute or two today by revving it really high but during that it crackled and popped like crazy and it sounded like it was missing once in awhile but not a constant miss. I also tried a tps reset and that did nothing. Where should i go from here is there any suggestions?
bike sat and now has un even spark and wont idle

Test your fuel pump. should be 49psi rock solid. If it doesn't pass take it out and PM Barrett for a re-build kit.

I would start with draining the old fuel and put in some fresh, check your fuel pressure like Cooter said and recheck the spark plug wires. Sometimes they can be a bugger to get on correctly.
