Interesting, looks like they tilt the carbs up a bit. Is that for crankcase clearance?

John,
Going that big on the carbs...do you get a kind of secondary Venturi effect as the mixture enters the smaller intake port? Are they designed to match a reed block or the cylinder. Appears to be the cylinder? Or do the reed blocks neutralize any of that potential? I gotta believe they have to taper down some to match the cylinders?
Enquiring mind need to know!

Not really, as the intake port will be matched to the adapter. One plus (beside the straight shot intake) is it adds some intake length/area, this allows for a bit of ram effect from the intake flow, also changes the intake wave timing to the carb. These adapters are actually for the guys running piston port motors.

I do have a Stage II reed conversion for the guys wanting big carbs and reeds. :thumbup:

Would they hurt using them with your stage one kit?

They look good, would make carb removal easier, with the 34's a guy has to do a bit of shaving on the carb bowls and I still have some trouble getting the left carb on and off.
Having a straighter shot can't hurt.
I have been thinking of making new spacers on the stage one kit, angled just a bit for these reasons .
Maybe this is the answer I was looking for. :think:

I looked, won't work, too different. If you cut a bit off the top of the countershaft cover, the carb comes off much easier.

That's to bad... more of a looks thing for me, it looks strange in my mind when ever I look at the cylinders angle compared to carb angle.

Looks like a good product :thumbup:

Thanks Joe! :thumbup: I'm not going to do another casting run for a while, but if you don't figure something out, I can probably modify a set in wax before casting.
