if you change the ratio check the jetting as well make sure your not to lean,a lil wet or dark brown is better than scorched, i hate to see someone fry their motor, this is just a suggestion , not bashing anyone
there are a lot of good oils, i prefer klotz 40:1
maxima, bel ray, amsoil , yamalube, hp2, golden spectro, xps, qucik silver, sno mobile oils ect...... lots of diff oils out there, its better to have a lil to much than not enough, just saying guys, a ratio tight cup is nice, but the cheap fuckers get cold and brakes easily
