Posted October 20, 200915 yr Hi folks - just a quickie - has anybody had any experience with running the Yam Yzf750r with no exup valve? I have seen some nice stainless headers on Evilbay that do away with the exup valve. Is there any advantage to this? or is it just a big headache? The advert says "no re-jetting required".......mmmm - dunno bout that one! what ya reckon folks? is it worth it? (my exup system is running fine at the mo - just the collector box looking a bit rusty!) - Many thanks all.
