I have read alot of threads on this forum about clearance issues with the seat post blocking the air filter from fitting on the 2 stroke kits. The 2 solutions to this are either to chop off a 1/2 inch off your intake manifold or to buy the the offset intake manifold from one of the vendors plus a new gasket. I found a way to get an air filter on without going through all that trouble.
Its called the Outerwear pre filter
