Well I fitted mine on thursday,bought secondhand with a map in it off a bike with similar mods,my initial run round the block wasn't good,been out on it today and it's settled down much better,certainley the surging has all but gone,but for you guys,up to necks in kids and mortgages,Kev's fuel mod more than gets the job done when your on the throttle, and if your in the West Mids I'll sell you one,although on thursday I was going to change it back !!!

Just need to get it mapped on a dyno now.
