Seem like you may now start sinking in that Needle Screw (little by little) and make that motor SCREAM !
Hey Buddy, I was at the track yesterday, the motor is getting close to be fully broken in, it is getting faster and cooler now probably a few more tanks or so!
Bottom to mid is very powerful but seems like rpm pick up is not as fast as JP and the top too!
after it is fully broken in I will put the JP back in there do a back to back comparison, and I will try different gearing too! (since this motor seems like it has more torque), I might be able to get away with 21t 2nd pinion instead of 20.
