In my journey to gain a little extra power, I baught the v-force reed system along with the FMF fatty and the FMF powercore II. At the same time I did a top-end rebuild. The paper work that came with the exhaust system recommended that I re-jet to a 165 main and a 52 pilot jet. It also said to use the 2nd clip position. Well, I went and baught these jets and to my supprise these jets are already in my carb. Even the clip pos is the same (2nd). The pipe also came with this little spacer and it recommended that I put it inline with my power valve "to reduce the dip in power" I havn't put it in yet, but I went riding after installing all this stuff and wasn't really impressed. There didnt really seem to be a dramatic change in the power. The spark plug looked good too. Is there any thing I might have missed? Or is that just about all im going to get out of this kx250?
