flyingchef - I have the same questions as tomrcnut
" Did you have to cut the cowl for the plugs? If you did, would the ME8 plug conversion that shaves 3/8" off the cap to cap width help? Did you put in baffles?"
Also, does anyone have any experience with the Valleyview 70cc twin - they advertise it to be 9 1/2" cap to cap
