Exploded view of CV carb

[Jack Klarich]

With a stock carburetor does modifications to the back plate help? Along with re jetting?
The bike I have has Vance and Hines pipes and no one ever did anything to the carb, I put a k&n filter on it and there's a noticeable difference. Now I'm just thinking of jetting the carb and opening up the plate. And I'm done.

Yup and Yup

Are there any diagrams of how to cut the plate?

Use your best judgement
You will be fine

Would doing it like a cal induction work? On the back side of the plate

Too much air is like not enough fuel adjust accordingly
You can add plenum by adding a longer intake runner more + gas = less MPG but OH Boy power if you are camed right

I would have to see the proposed backing plate modification to respond one way or another. If the carb had not been re-jetted to compensate for the A/F changes associated with a hi-flow intake and exhaust; re-jetting would probably make more difference than any backing plate modifications.

What's a "cal induction" anyway?

More Plenum and more fuel plus cams EH

Yeah, spell check on phone isn't the best thing sometimes..

Dolt, pipes were added to the bike, it had a stock air on it, nothing else, I put a k&n filter on it instead of the stock, I can see a difference. But l know that it needs a size up jets to get the most out of the pipes and filter added.

Next question is... How do you use the quote function on this board?
