They dont fit that bad. I have more room around the carburetors than I had with my t5's. The cpi's curve out and then tuck back in. With my toomey, boss racing intake, pwk with pods had less room at the carb cap. I had to have my LH carb turnd a little so it woldnt hit on the pipe. My cpis curve out and around.
I had to put 1/4 or 3/8 in spacer between the front pipe hanger and the frame. (if you have a hardware store that sells those chrome fastners that is what I used insead of a stack of washers.) You will also have to trim the front fenders if your running full fenders. I run the cascade exhaust wrap on my LH singer tube so I dont have to worry about melting any outerwears.
On my motor the gain was deffinatly worth it. If you get some cpi's i dont think you would regret it. I just figured that your going to have to modd somthing to get those huge cpi's to fit. I can get some pics if you like.
