It says to use parts solvent in the manual, to clean the air filter. I used some kind of parts cleaner in a SPRAY CAN the first time i cleaned it (don't remember the brand). Then washed the parts cleaner out with warm soapy water. Just curious to know what everyone else uses to clean theirs?? Spray can or not? Brand? Or does it even matter? I know you shouldn't use the spray type oil to oil the air filter as per the owners manual. I just put a small amount of motor oil in a large ziplock and put the air filter in that and squeezed it around for a minute or two. Got that idea from the yamaha place where i bought my wolverine. Mainly just wondering what kinda solvent people use to clean their air filter with, spray or not and what brand.
