It sounds like your ready for a change, I would recommend a 1960's Panhead or a 2000 Buell. They have tons of character, never get boring, and should be as reliable as a BMW, if well maintained and not beat and abused.
Oh, the Pan Head will test your metal. You have to gauge the temperature of the motor, ambient air temp., how much choke to use (if any), and how much spark advance, then kick........ JUST TO GET IT STARTED! Its a love/hate thing.
