Can someone tell me how many mile you can go average on a tank of premix until you hit reserve? I'm talking average to fast trail riding. I have a 99 KDX 200 jetted down to a 155 main and a 45 pilot with the air box lid removed. One more question, has anybody tried the torque ring from Fredette Racing? Does it work and does it kill your top end on this bike? I just installed Boysen 607 power reeds and they seemed to help out the bottom to mid range on my bike. Thanks for the advice.
