Anyone got a stock intake and a caliper ? Can you measure tube size id and od. Also distance between the two bolts? Tom

Why would I need a caliper? I have it memorized.
The distance between the two bolts is either 32mm or 40mm
The OD is 19 mm and 3/4" will work.
Why do you need the ID?

IIRC the opening for the inlet port on the cylinder is an oval shape, but the restriction is where the carb clamps to the spigot of the intake manifold.

The engine is an old bike bug on an old worksman mover trike used to putt around cirsfield md . The pot metal inlet got broken in transit when the bike got loose i in the pickup truck. A replacement is not possible new. Mike Snyder at bike bug might have one but one of the kind that you all have might be able to be modified and work . Looks like it's close. Steel is workable for me pot metal is not. Tom the old hippie

most are zinc plated mild steel, but some cast aluminum ones exist. I think the supposedly aluminum ones are closer to zamac, not worth trying to weld. though I think alumiweld rods should work on them.

The metal seemed to crumble in my hand. Outside in the grave driveway I was unable to retrieve all the pieces. I hope Mike can find me one. The bike is perfect for me being well made and considering my disabilities. I have two bad knees and a hip from accidents and balance issues. Being an old dude the trike and low speeds work for me. This is my forth b bug classic. One sold one stolen and one lost to fire. The trike is a one gear so next is an upgrade to three speed. Be safe Tom
