Hello all, I'm new and have a question. I just got my 2013 Kawasaki Teryx Sport 750 2 seater engine rebuilt with an 840 big bore kit, also added a sport utility clutch kit, high performance air filter, a Power Commander V, and dual oxygen sensor auto tune kit. I have way more low end and mid range power now which was one goal. One big goal of getting the PCV though was to raise top speed (I would be happy with just a solid 55mph). However, after using rev extend option and getting the code to raise to 8700 rpm, I still can't get past 50mph! I hooked my computer up on my last ride and even on a paved, slightly downhill slope it showed that I'm only hitting around 7950 rpm with pedal on floor? I'm confused. Running stock 26" tires and stock exhaust. Any advice would be great!
