Question about 2007 HM CRM F490X I
I'm new to the site and new to carbs. I bought a bike last week that had been sitting in a barn for a couple years the engine hadn't been running in over a year. I was able to get it running the first day after cleaning out the field mouse home occupying the air filter chamber and swapping the old gas for new gas. The bike ran and idled fine but the left carb (dual carb setup Keihin) poured gas from the tube coming out the bottom. I did some research and found out the floats may be stuck. I went ahead and ordered new floats and float bowl gaskets. I took the carbs apart apart as much as I could, using Berryman parts cleaner to soak all the metal parts I could get off. I put everything back together and put the new floats in yesterday. I started the engine and not only is the gas is still pouring out the bottom of the left carb, but now the bike is idleing very fast. The idle adjustment is backed out completely. When putting the carbs back together, I screwed all the jets back in all the way. I screwed in the Pilot Air screw, the one with the spring, all the way in, then backed it out 1 1/2 turns. Not sure if this has anything to do with the idle. As far as the floats go, does it sound like I need to replace the float valves too? ,The seats on the jets, or the o-rings on the needle valves that the floats control are probably leaking.,,,
