I had to add about 1/2 of rise to make my air cleaner setup clear the new electric choke assy on my e-brcok performer 650cfm carb, which is way enuf cfm for street use of my W72. I bought one of those Mr Gasket air cleaner riser thingys and dremel tooled it down to half of its orig. height, I really really didnt like the idea of bolting the scoop to the hood, I thought that was kinda way too extreme, I love opening the hood and seeing the shiny red under there, that and hitting the throttle and seeing the shaker move, even if it is only a small amount of movement. I went to an auto parts supplier to get my paint matched and I took the shaker to do it, the guy there said, WOW I dont see many of these anymore, and he was right, that made up my mind to keep my shaker, well a shaker.
