New Intakes Too Large and Rub on Tin Question

[camit34]

Did some looking around and did not find anything about this

These intakes are from CB and for the IDF 40s I'm going to mount.

They are too wide to fit due to the tin. There is no room for me to bend the tin out of the way, so curious of you would grind the intake (it's pretty thick right in that spot) so that it fits.

I cut the tin at the spark plug hole at the thinnest point at the bottom by the intake gasket, then bend them in behind the manifold. It just takes a tin snip not metal removal.

If you have good German tin, grind the manifolds.

Make sure to clearance the manifold flanges to clear the hold down nuts. I found that the nuts would fit on the head studs. But without a washer.

Also you want to be able to get a socket on the intake manifold nuts. So you may have to clearance the manifold above the head to intake flange as well.

These dual carbs can be a bitch to install with the engine in the vehicle. It's a good idea to have a 1/4" drive ratchet and extensions. Sockets too, to slip between the forward manifold hold down nuts and the forward tin.
You'll see what I mean when you install the engine and carbs.

Good Luck.

Don’t forget the vacuum port for the booster.

That’s a bunch of work to do by Saturday, I hope you pull it off!

Either way those carbs and that VS exhaust is gonna give that 1914 a whole new feel. Stoked for you!!!

Make sure the manifolds slip on with both the cylinder tins and fan shroud bolted together. Sometimes the shroud will push the tins outward and this will cause more interference.

Update? How’s the day go?

Just washed mine and packing now. Hoping to leave around 11 tomorrow.

I would set them up on the engine out of the bus. Including the linkage, making sure it has WOT, float bowls set, fuel lines run (depending on your plan with those) and all. Then install, it’ll be tight and you’ll have to angle it a bit to get past the rear apron ears, but it can be done.

Did you get the vacuum port drilled and tapped?
