I'm after advise on what I should be looking to do, my xt is one of those suffering from being snatchy and surging, so far cutting the groove in the throttle tube looks a good idea, maybe a DNA stage 1 or maybe keep the stock filter as they are mostly sand tracks, I'm also thinking about the kev mod. I'm looking for the best value for money mod wise. The bike is 2006/7 and so far as I can see it's fully standard.
