Part Number: 39-416

POWER TUB - Part Number 39-416
New Master Kit Includes Adjustable Needle. A new Yost Power Tube specifically designed for the stock H-D CV-40 type carburetors (1988 & later). After intense research and development, Yost has developed a Power Tube that is not only very easy to install, but it also transforms the stock CV-40 type carburetor into a very competitive, high performance carburetor (equal to or better than many other high performance carburetors and cost much less than the competition!) Don't be mislead, this new Power Tube is NOT a tuners kit; it is different in every way from anything else available today and is unique in form and function. What Will The Power Tube Do? * Gives the customer the best bang for his dollar. * Machined from solid brass and completely U.S.A. Made. * Atomizes the fuel, creating a much more efficient and cleaner burning fuel mixture. * Specifically designed to sychronize the engine demand with the air and fuel requirements (in other words, this new Power Tube gives you the proper amount of fuel at just the right time). * Provides an almost unbelievably smooth transition and throttle response (almost eliminates any flat spot). * Very easy to install (approximately 1 hour). Complete instructions included.
