The carburetor on my 2005 Honda Shadow Aero (VT750C) had a bad leak and flooded the air cleaner assembly with gasoline. The air filter was completely soaked with gas, so I let it air dry. Is my filter ruined, or is it okay now that it's dry?
The last vehicle in the USA to use a carb was the Susuki Jimmy in 1993. Your air filter element is bonded together with petro-chemical adhesives, and a lot of filters have a petro-chemical treatment to enhance thier performance. Soaking the filter in petrol can only be detrimental to the filter. Your best bet is to change the filter to avoid any possibility of it breaking pieces off and causing problems in the manifold or throttle body.
