QR Code Link to This Post By Far the best thing you can do to your stock Harley Carb. This is basicly a tube-in-a-tube emulsion tube that makes your bike run SOOO much better!!! Read below for more info: Been installing Yost Power Tubes in Harleys for over 18 years (Authorized dealer). The Kit is $102.00cash. If you want me to install, labor to install, modify, and "SuperTune" your carb is $50.00. Most need a new "#45 or #46 slow speed jet" which is not included in the kit, but everything else is. Also, have Chrome carb tops for $15.00, no labor because it is already apart. Call show contact info 9am-8pm with questions or to make appointment, no text or emails please. Below is more information from The Yost Website:There are several benefits when you use the Yost Power Tube. 1. Produces a very fine mist The Yost Power Tubes by design, produce a very fine mist, finer than most production fuel injection systems and can be seen and observed by removing the air cleaner and looking into the carburetor venturi. (BE CAREFUL, WE DON'T WANT YOU TO BURN YOUR EYES, NOSE, OR ANYTHING ELSE.) This very fine mist allows the fuel to stay in suspension longer for better control of air and fuel mixtures and can be almost perfectly matched for almost any throttle position. 2. Mid-Range Power and Horsepower One of the Yost Power Tubes greatest benefits is extremely good PART THROTTLE response and MID-RANGE performance. This is the most affordable horsepower gain that money can buy. Typically, there will be an increase of 2-5 horses. 3. Increased Combustion Efficiency The Yost Power Tube provides increased combustion efficiency for a more complete burning of the fuel mixture so that you need less fuel to do the same job. The Yost Power Tube is specifically designed to synchronize the engine demand with the air and fuel requirements. (In other words, this Yost Power Tube gives you the proper amount of fuel at just the right time.) 4. Smoother Running Engine You will have a smoother running engine through the entire range, due in large part to the increased combustion efficiency. There is a greatly reduced possibility of pockets of raw fuel burning randomly. .....Punch-in our phone number in "search" to see our other ads.====Ride Safe====
