Is this intake designed to mount directly to motor to use bigger carb while using stock reed block?

I DONT KNOW. I came across the same thing It sure looks like it is. I dont think I would run a 26mm threw the stock reedblock. This would be great for the smaller carbs by the look of it.

Yes, but it uses the stock reeds which are pretty small and will negate most of the bigger carb's effect. You would be better off getting a CT manifold with it's bigger reeds for about $10 more.

Yeah, the extra $10 is worth it. I was curious since i never heard about just the manifold.

Honda is known for limiting engine performance by using a small carb. Compare the 1983 thru 1985 Aero 80 carb at 16 mm to the CR80R of the same era with a 24 mm carb. Can you say "Not enough carb?"

I was under the impression that the biggest carb on a 50 cc motor was a 16 mm PB series with the changeable slow jet. Oh and that 16 mm carb has a venturi as tall as the Aero 80 16 mm carb but is about a 1/3 less wide. At least that is the case of the set up I have sitting here in the shop. This is also the reason I hate this measuring carbs by the venturi height and not their air flow.

According to the service manual in the "Owners and Service Manual" forum on this site you have a Keihin PA35J which is a 14 mm carb.

My question for you is why don't you have this service manual download to your computer so you can look it up yourself?
