Hi, what is the best (maximum) sizing for the primary and secondary venturi's in the 4 barrel nikki

on a 12a NA with mechanical secondaries for circuit racing use. Any info and experiences

appreciated thanks.

I don't believe that you want to mess with that (or jets) on a stock nikki. If you're looking for more power, check out a Sterling modified Nikki. I have one and can tell you its awesome. Flows much better than stock, and is good for anything you'll be doing to you motor in the future (porting, etc.)...

 

Hi kentetsu,

thanks for the reply I am sure that the Sterling carb and the Yawpower carb are both excellent

however they feature mods that are not allowed in my race class which is why I am looking for info on the best

(largest) venturi size combination that works.



Regards

Michael

 

Sterling will work with you. If there are mods you can't have, talk to him and get a carb built to the limits of your class. If he's to busy, try talking to Carl (PB&J Racing). He and Sterling partnered to build the carbs, and I believe he usually has less work load. He built a Nikki for me that ran strong.

 

Sorry man, I didn't understand what this was to be used for. As was already said, Sterling will work with you based on your needs. Customer service and support is outstanding. Check out www.sterlingmetalworks.com for more info.
