Yeah semi downdraft carbs. Those are good and very compact, my favourites, bore spacing is good for a series too.

Good choice.

Mounting them on an angle will also let me get them closer to the engine without having to clear the extractors.

What degree angle do I mount them? Should I look up how their positioned on the original bike and try to copy that positioning?

Your level line is where the carburettor bowl meets the carb body.

Oh yeah I see where you're coming from.
Will be easier to understand once I get it and I can have a thorough look at it.

Ok here's a question, how do I run manifold vacuum to my brake booster with these carbs?
Drill and tap each runner, screw in piece, run hose from each into a 4-1 mini collector, then hose to booster?
Removing the booster is a no-go, to much work into getting it in there?
Could this be the deal killer?

Don't worry, figured it all out haha

ohhhh i so wish i understood how to set these up more, id love these carbs to swap back to petrol in the future.

L series and Ka24de head with quad carbs = winner
