yes dan, manifold build for gl1200i its the type 3 vw plenum with stock 1100 manifold elbows 1-1/4 aluminum pipe nipples turned in lathe to fit in rubber 1" sch 40 aluminum pipe joining them contoured internally to better match each end with tom langdon's 32/32 progressive bolted on top. oh and i had to weld the vacuum port shut on the manifold because i cracked it trying to get a brass plug to seal. after initial fire ups and vacuum leak chasing ii ordered a few idle,main and air comp. jets i dont recall what exactly i have in there now but i know the 50 idle had me turn out 5 complete to get it to 1000 rpm smoothly,so i put a 60 in there and get the same results with only 3/4-1 full turn out from seated on the mixture screw. As far as performance it sure likes wot. into the secondary mid range cruising is ok, im guessing it gets around 33mpg combined city/highway. I dont know about my butt-dyno i need a second opinion sure wish some you guys lived closer.
