Hi last year I put new castrol power 1 oil,yama oil filter, exhaust gaskets, iridium plugs and kandn filter on and had it tuned by top guy who has the dyno computer and he said its making a noticeable lot more power than other ones he's had in. It also felt a lot quicker and sounded meaner too with delcevik exhaust bike came with. So I don't know whether it was just the filter or combination of everything but what sold me on it was its good for the life of the bike and the air filter is a bit fiddly to get at for changing the cheap ones all the time.
