hi guys just fitted a 650sx nozzel to my sxi took it out today and found it had a bit more bottem end but felt like it was cavitating and was bouncing on and off the rev limiter dont know what pitch the prop is but im curious as to what it would be like if i installed a skat trak 9/17. Im thinking that if it is on the limiter and cavitaing now what would it be like with the 9/17 any advice would be great cheers.
