Re: Nasty gunk in air box?
OEM air filter. It has no oil on it whatsoever. Looks brand new. And bike hasnt been on its side since Ive owned it. Im thinking it might have been from the oil being on the high side. Im not thinking blowby since it doesnt smoke. (Unlike my turbo Mazda who just went through its 3rd motor this year)
Did my bi weekly oil change on Saturday and ensured its back in the middle of the dip stick.
Ill be due for sparkplugs again before January so ill report my findings then to see if its returned.
