Ok, so I did this test over night. Disconnected hose from check valve, removed check valve from carb, put the check valve back on the hose, and placed it in a solo cup. There was indeed oil leakage, but not that much. Just enough to put about a half inch ring of oil in the bottom of the cup, which i think would explain my problem. It seems to take about a week for my air filters bottom half to get soaked with oil. Of course now that I know I clean it everyday.
So I guess I need a new check valve. Do you sell these check valves? I was unable to find it listed on your website.
Also I lost my key when swimming in the ocean (forgot key was in pocket) and was wondering if I have to buy a new ignition with a key or if its possible to get a blank and have a locksmith make the key from my ignition.
Right now I just unplugged the ignition, but it leaves me kickstarting and more importantly without brake lights, turn signal, or horn (nearly saved my life a few times from lane switchers not paying attention). I figure if I'm ordering stuff I might as well do it all at once.
Thanks again for your help.
