UD Racing Boost Bottle for ATV Pocket Quad (air-cooled) - Blue Description

This boost bottle can be mounted on all stock ATV Pocket Quads and all ATV Pocket Quads with a Racing kit.

Working principle: All 2 stroke engines without a reed valve will end up forcing mixture back into the carburettor during part of the piston's cycle. This mixture will be sucked back into the engine during the next cycle. Since it passed the carburetors needle twice (or even three times) the mixture will be far too rich to burn correctly.

This will not damage the engine or foul a plug, but it will decrease the performance of the engine slightly. A boost bottle fixes this problem by catching some of the mixture backwash of the engine before it makes it to the carburettor's needle and then release it during the next cycle.

By ensuring a consistent mixture ratio, the boost bottle main benefits are sharper throttle response, faster speed changes and improved fuel economy.

This kit is used in competition.
