i've got 14/39 gears in mine and although i like how it stretched the gears out. i did notice the loss on the bottom. i used to start a race in second, now im back to first gear again. i've got a spare exhuast cam for it but i cant justify working on something that runs while i've got stuff that doesnt. i changed the rear so it would be smaller i have an issue with bending the x package skid into the sprocket.
