  1. yamaha xl700 issue

    Been working on a 04 yamaha xl700 for my brother and it just doesnt seem to get up to speed. I have inspected the pump housing and rebuilt, wear ring to impeller is .30mm gap. rebuilt carbs and replaced plugs and just cant get over 30mph. compression is 120psi for both cylinders (Did forget to open throtlle WO when I tested) There are numbers on the back that may suggest that it was a rental, butterflies do open fully. Am I missing something?

I fed the 160's w/ the 1/4 line that came from the WB regulator-- start with the regulator turned all the way in and tune from there-- relative to water temp you run
