ok so a few weeks ago i took my quad in to have some work done i got an ESR pipe, stage 2 hot cam, K&N with no lid,..and a dyno jet kit.i also have it geared closer for my tall knobbies. well it hasnt been right since..i took it back and he made it better but still not GREAT like it should be.. he warned me about the dyno jet needle and how touchy they were but i never had a stock one so he went ahead and used it well heres the problem in town its lean i think.. pops and back fires a lot.. now at dumont it didnt pop or anything it just fell on its face as soon as i hit a hill.. there not that big of an elevation change but i need some advise to get this thing right.. blue has a pipe and filter and same size paddles but stock gearing and hills his bike will do in 4th all day long i barely hit in 2nd.. should i get a stock needle and put it in like blues bike has? can wildcard or alfie get me one?
