The intakes are sold out for now July 24 2012 I will turn on sale button when I get more.
Very popular kit put together from top brand name products from NCY, EMGO and Keihin.
The air tube fits perfect under the swing arm bar with chrome EMGO air filter installed on the end of tube.
The idle jet is 45 with your choice of main which for stock engines without exhaust or cylinder kit 120. With exhaust of larger cylinder kit go with 130.
GY6 150 engine can stand better fuel and delivery to get overall better performance.
Adding a cold air intake along larger idle and main jet helps with bottom end and midrange with just the right amount of air.
