The DaVinci Fire Power Carburetor is a true performance upgrade from the original S&S G.

All DaVinci did was bolt on the DaVinci kit and the bike produced 99.6 hp and 107.8 lb-ft of torque - a 5.5hp and 5.2lb-ft of torque gain in 15 minutes! Using a hex key, DaVinci bolted the backing plate into the head and put the air cleaner and cover back on in preparation for our second dyno run. We then, screwed the new discharge tube into the main discharge tube hole along with the included jet, just as we would with a normal S&S G carb.ДonвЂ™t forget to put on the float bowl gasket, then screw the float bowl back into place. Then, we put the anchor and socket into the main discharge tube hole and tightened it down snugly.

To install the kit, we simply placed the booster anchor into the supplied socket wrench with a little Loctite on the threads and placed the booster inside the venturi of the carb. Here is the entire DaVinci kit: a special booster anchor socket wrench, Loctite, annular discharge booster, booster anchor, discharge tube, and main jet. Next, the main discharge tube was pulled out of the carb body assembly, so he could install the DaVinci kit. With the air cleaner assembly and backing plate removed, DaVinci drained the fuel in the bowl, removed the float bowl screws, and then the bowl itself. The вЂ™03 Big Dog Mastiff with a 107ci S&S and a stock G carb, the stock Mastiff put out 94.1 hp and 102.6 lb-ft of torque. Follow along as DaVinci and Nigel Patrick show us how it is done. Dan DaVinci likes the S&S and came up with a fix for the pop, then went one step further and completely modified an S&S to show some additional power. Long-time S&S users know that the G has a decent stumble and pop at low throttle as it transitions from circuit to circuit. The S&S G has been an industry standard for as long as anyone cares to remember, but like anything else, technology can always improve it. It is pretty common knowledge that a big motor needs a big carb.

The second portion of the article describes the DaVinci Fire Power Carburetor, but by installing the aforementioned booster kit you should be able to achieve similar performance gains. The upgrade was performed on a Super G model, but also applies to the Super E model. The following article describes an S&S carburetor upgrade by installing a DaVinci Booster Kit. Unfortunately they are also known for hesitating off idle when opening the throttle or experiencing a stumble through the circuit tranistions. The S&S Super E and G carburetor has long been a favorite performance upgrade for Harley motorcycles.
