Can someone help me get this motor running good. Its a Eric Gorr 144cc ported for low mid . It has no low end no top and no hit. Just a surge in the uppermid.Ring gap is .20 thou. squish band at .45 thou. Using C-12 race gas. I have spent manny hours trying different jetting combinations. Right now it pulls about as hard as my friends stock 02 yz125. But his bike has more bottom and more on top. I have spent a lot of time and money on this bike any help would be much appreciated.
