These carbs are off a bike w/26K miles, might make a killer setup for someone w/a hot 350-550Four motor? Haven't torn 'em down(too many projects) but manual choke works smoothly on all 4 carbs, barrels, slides do not appear to be gunky,bike has been garaged by PO's disgruntled girlfriend(hey, at least she kept it in the garage, right?) . These are much easier to tune than Keihins and will run like stink. My email: torrencebirdsong@yahoo.com, or call me, Tory @ 512-535-8685, thanks Have slideshow of carbs,shoot me an email
