The carbs are OEM on many dirt bikes but those are slightly different to the street ones.

The FCRs, for the most part are aftermarket racing carbs.

As I mentioned earlier, be prepared for some sticker-shock.

I wont be doi g the fcr carbs right away. Keeping that idea for later.

Anybody have a guide or tips on how to size up bike carbs for a car engine?

Somewhere on the net is a carb size versus horsepower per cylinder but I can't find it.

My car is pumping out about the same as older 750cc bikes and those used 39mm so I was fairly sure they'd work. Slide carbs without the throttle butterfly flow more than other types. I do not how know bike CV carbs flow rates compare to traditional DCOE type; they both have a throttle butterfly so I'm assuming they are comparable.
