ST250 Upgraded Air Filter

Fitting upgraded air filter from the stock air box.

Q : I’ve just upgraded my air filter from the stock air box what do I do with the two extra air hoses left over?

A : You can put a little filter or a catch can on the shorter hose coming from the engine as this is the engine breather. The other one is the exhaust gas circulator which can be lead up through the frame and fixed up there.
