well, you didnt say who did the porting. i just assumed it was some no name builder.
you could go to prostlers in topeka or GTperf in dearborn and run it on a dyno to see.
did anyone notice the industrial size starter sitting on the ground next to it? when a bike needs a big heavy duty starter you know its making some power.
ive never worked on a bike that didnt require a 27.5 pilot after putting on pipes. stock is 25. i think you will need to change the pilot. leave the needle alone.
