[QUOTE="westgl, post: 100484, member: 2025"] Since our[b] Carb.[/b] for the New Single carb Conversion is way up stream, of the head, it is very hard to compare the OEM carb and to use any dimensions from the OEM carb as a size comparison as flow is going through the closer to head placed OEM carb. and i do not think they would act the same way. But looking at the GL1500, That is a Much better comparison to what we are doing. I would like to look at a GL1500 Intake manifold, and Carb. off of the bike. I would like to see the ID of the manifold to see any tapering, or reduction in ID, and also look through the carb. as that carb is a down draft carb. It may be different. But, It would be good to look at. I may have to Call my Friend at the local Cycle salvage, to see if he has a GL1500 intake manifold, & Carb. he can lone me for a couple of days I would love to take some measurements off of the GL1500 parts. I think that the head intake port & intake manifold flange at head mount, is a much smaller ID on the GL15, than it is on the GL11 or GL12. The GL15 appears like it has a larger opening at the carb and gets smaller at the head, like the Venturi I want to make. Could Honda have this all backwards on there later version the GL15? We are soon to find out. [/QUOTE]
