yeah, it looks like a pretty decent carb.
I downloaded the install manual from racetep. it was nice to see some CLEAR install pics. the stupid "manual" that came with my 32/36 from Redline Weber sucked ass. I felt like a guinea pig on that one, even though I'm sure they'd sold hundreds of kits.

it looks like Racetep's put together a pretty decent bolt on kit, though, so that's a plus. but how does it run? that is the question.

I like my 32/36, though my mileage isn't so hot -- only 18mpg in the city if I'm lucky. I have a 40/40, as well that I was gonna work on this summer, but the 34/34 might be juuuuuust the right middle of the road balance between the progressive carb & the bigger synchronous carbs. but seriously though, can 4mm of barrel diameter really make that much difference?

I wonder what size venturis are in the 34.
the 32/36 has 26mm & 27mm ones. I think the 38 has 27mm ones, and the 40/40 has 28mm venturis. so, that's really not a whole lot different between the three models.

we need some hard data from someone who knows what they're doing!
