Carb clearance

[graggy]

Has anyone here used an offset 40mm carb intake? If so how did it work and what is a good one to get? Any recommendations?

What frame is this on? Do you have the ability to move the engine forward? The rear engine mount is designed to be able to be shimmed/spaced for both chain and clearance purposes. Longer studs or bolts may be required, but a spacer would be easy to make as it is literally just a rectangle with 2 holes in it.

I’ve got it moved about as far as I can. Still need room

The top part is easy to fix, just turn the carb a little bit at an angle, you would be surprised how much of an angle you can set your carb and still have it work. If you can't adjust your engine mount, you could try one of these intake solutions.

Haven't used one myself but here is a "Z" intake I found that should work for you if all else fails.

I used the short one, works great!

I like the stubby intake manifold. It performs better than stock, it looks good, and it has a built in o ring seal.

You can make an off set from a 3/4 45 street fitting. With o rings home made set screw and the right sized pipe it will work just fine. I did luck out with a piece of towel bar rod and some thin walled pvc pipe I had kicking around.

YEP...That would also work fine as a zero cost solution...Much better air flow as well.
