Hey all.. been fighting this problem for a while and tried some suggestions from here but nothing seems to help. My son has a 2009 Honda Rebel CMX250 and within a few days after changing the oil it appears gray and milky. I have drained the puke tube and blew it out with some low pressure air but still an issue. Recently I have cleaned the carbs, replaced plugs, basic maintenance stuff. I assumed it was due to his short rides so I had him do some longer runs to bring up the temperatures but no difference. Any additional suggestions would be greatly appreciated!
