my bike(96cr250) feels a little flat on the top end. ive gone down to a 170mj from a 175 but the 175 will go back in when it gets cold. i understand that this bike stock has a low-mid port but do you think a little more top end could be established for my warm weather riding? like a 172-3mj? do they make one? would the make a difference? also i now believe how jetts can vary from their size regardless of the # stamped on them. also where can i get honda hp2 premix in bulk? $6.00 is a bit much for 4 gallons worth of gas.
