has anyone installed the replacement air cleaner using the stock exhaust? If so,did you experience running problems.How about an exhaust mod like the hindle or other set up?Thinking about the kewl aircleaner just to clean up the engine compartment and make things easier to access,dont want to go the juice box route if I dont have to,bike runs great now w/supertrapp pipe and green flow aircleaner.Thanks in advance!:dontknow:
