FUEL ATOMIZER MASTER KIT FOR KEIHIN CV CARBURETOR

• Totally eliminates the spitting and popping that the 40mm CV carburetor is prone to do
• Improves throttle response dramatically and will increase power by up to 5 horsepower
• Fully adjustable for everything from stock to highly modified engines
• The flow control needles feature 6 different settings for exact mid-range tunability
• Includes 4 main jets with sizes from 165 to 195
• The Power Tube (emulsion tube/main jet holder) has been redesigned to be used with the OEM main jets if larger jets are required
• The secret to the patented Yost Power Tube is its ability to convert the raw fuel entering the throat of the carburetor from a squirting liquid to a fine mist. The atomized mist will ignite easier and produce a more complete burn
• Installation instructions are included.
