I guess I'll chime in too, I'm rebuilding my entire motor and had a 2-5 override out of another shee that I parted out. I'm running stock drag ported cylinders by fast and a stock stroke long rod, v4 reeds, shearer small bore, 34mm pj carbs pump gas. would it be a bad idea to run an override, I don't trail ride it much just ride the shore line and drag race and go to little Sahara ok a few times a year?
