I want to place a fuel filter in-line since i've had some issues with carb despite cleaning, rejecting, and now cleaning tank. I just want a fuel filter as suggested here to eliminate that chance. PO had left gas in bike for over a year or more. Cant find in manual, online, or here exact size of the fuel line. I do not want to go cutting the line to insert filter unless I have some backup line/hose available. I also need to know what size filter to order based on hose diameter. Sorry for the simple question. I have looked and all I keep finding is carb vent line sizes, of which there seems to be some discrepencies depending on the post but no worries there I'm not buying those.
