You need to do a bit of reading around the fuelling threads within this forum get yourself familiar with the issues that cause the bike to surge and cut out, no 2 bikes behave the same but generally one time or another they all pretty much suffer from these occasional problems. There are a number of ways to interact with it and one is altering the CO1 level on the diag mode and other will be to fit a fuelling mod such as the Kev Mod much cheaper and similarly effective as a power commander which will be you other option but obviously more expensive, meantime we suggest you alter the CO1 and remove the snorkle or drill extra holes in your air box see again threads on how to do that, allowing the bike to breath better and burn fuel more efficiently.
