At around 250 lbs, this bike should be nimble as hell. You are adding some lb's to it with the bar clamps , but losing weight on the exaust....Any thoughts on going to one of the lithium batteries to keep it on a diet? I picked one up at the ktm dealer and thought it was impossible to be that light. I'll be doing a similar build as you....great thread...
