Fit them so that the float/fuel bowls are level.

hey thanks for the reply.
i just got gsxr750 carbs there is approx 5mm difference overall on manifold spacing.
i have more questions. wot is best way to block up the injector holes in the head and also any idea of power gain on a standard engine with the carb settup.

Add at least 10hp, depending on engine condition. As for blocking up injector holes....you can either turn some small tapered plugs and tap them into the holes with some sealant....ot you can use some high-temp sealant to fill the holes. Either way works just fine.

I used the R1 carbs on my car instead of the GSXR carbs as they were smaller, lighter and newer...but the port spacing was certainly not as nice and close as the GSXR's. Which GSXR's did you get - the 40mm's? I know of someone who used an early 36mm set but ran into fuel supply problems due to the tiny fuel bowls on them.

hi oz. yeah the carbs are 38mm, but i've got gsxr throttle bodies coming they have same spacing but 42mm bores. i can use my same manifold just port it out more, something i'm unsure on is the angle of the carbs . the bowls are level but the gas will enter the head at a 40 angle(down before any1 asks) and i'm sure this is'nt ideal. guess i'm gonna have to get the head and manifold and put them on a flow bench.
pics soon.

hey oz. i've seen your name come up a lot when it comes to carbs. do you think it'll be worth me making more manifolds to sell. i've got a contact to have them casted in ally and also carbon on a ally base plate. latter is easier to port out. i'm just not sure wether its worth it considering i can't cover every carb size, spacing and angle.
cheers

GSXR and R1's seem to be used most, and also Webers. Do an EOI in here and for sale sections, perhaps.

My carby pics are in the gallery here.
