|What's your question?
||Are an 80ci and 74ci intake manifold for evo's interchangeable?
||I want to use a different carb for my build but it only comes with a 80ci conversion kit.
- If i was challenged with this problem I would cut the end off the manifold that fits my motor & weld on that part from an intake that fits my carb. You would end up with an intake that fits your motor & your carb for very little cash.
I have not seen your set up so this is a blind answer but in theory it would work well!

- Thats kind of what I was thinkin. Thanks Hatchetman. Looks like I have some work ahead of me. By: Sword on: 2-10-2010
- I use to run a 40DCOE Weber on my '69 Shovelhead and had 2 manifolds made by Sandy Kozman, in San Francisco. One manifold was a split manifold and the other was a common manifold. The split manifold seemed to work better in the lower end.
As to the 40DCOE, that was the best carburetor I'd ever run as it's the state of the art when it comes to German workmanship. But...it was a pain in the ass. First, securing the carburetor because of its weight. I had to make a bracket that bolted to the carburetor and then to the top case bolt. Then I found out that the Weber likes to run at a 5 degree angle to the engine in order for the floats to sit right. Then the sumbitch wouldn't run right on gravity feed and I had to add an electric fuel pump.
Then, the fucking carburetor would leak into the manifold when I parked the bike on the kickstand. Before I could kick it over I had to lean the bike over on its right side and drain the gas out of the manifold. I bought my Weber at a British Car dealer in San Francisco, then after it was all mounted and the quirks taken care of I had to go to a racing sports car place that had a Weber tune up box and dial the carburetor in. Then I had to buy extra emulsion tubes with different main jets, air correction jets, etc. for high altitude. Then the bitch wouldn't run for shit on velocity stacks and I had to put that fugly square air cleaner on it.
I'll have to say...it was impressive looking, but its best function was a leg rest on long rides.
Good luck! By: 47Knuckle-Dragger on: 2-10-2010
- I've been goin back and forth with Erik Buell on this one. He's the one that suggested the weber, but It was partly out of being a smart ass. I was also thinking about doing dual SU's. But then I still need to get, fab or find a couple intakes for that app. I'll probably just do the S&S E and be done with it. Nice to dream though. Thanks for the story and advice 47Knuckle-Dragger.

- The fab thing seems more better to me. Besides, it's cold outside and the work will keep you warm...
However, I would think that there is a manifold made by someone, somewhere, for a nominal fee, of course. By: capnbill on: 2-12-2010
- You're buildin my next bar hopper. I hope to find BUELL wreck, find a early 70's sport frame that I use the neck from on to a hard tail frame. Can this be legally done ? registered as old frame with replacement motor? then I want a quick-connect JAWA type side car. am I dreamin this can work ??? By: wingman on: 2-13-2010
- You should start your own thread for that question. By: 47Knuckle-Dragger on: 2-13-2010
- I was running a turbocharger on my bike same issues intakes were not matching up. Split the intake and welded the mess together fitment problems down line occured. In a moment of frustration I used a rubber coupler with two stainless steel hose clamps to splice the intake together. It worked great. Vibration from motor was isolated from turbo, not my intent but what the hell it worked better than I thought. By: MarkGoff on: 2-15-2010
- K/D, I've been tryin to post the question multiple times, not accepted, shifts me to B&F, won't accept my app., won't upload. whaddo I do ? who do I call/(isit local/) wing By: wingman on: 3-8-2010
- I'll test drive that, see what I get. If the test posts, then you're doing something wrong.
[EDIT:] Works fine for me. Try it again. If you get the same redirection send Chopperguy an e-mail describing your problem.
