    Folks,

    What mix are you guys runnnng with the modern oils ? 25:1 listed for back in 1972 but today’s oils survey this can change ? My ‘72 WR runs well but it is (I think) over smokey.....

    Thoughts ?

    Cheers Craig

    The thing to remember here is to use lots of oil but if it smokes then use a lower grade oil that will burn off at the heat you are producing.
    Not top motul 600
    Good oil but less of it will still smoke but just give the bike less lube

    I run 32:1 in everything because its easy to mix, 4oz for every gallon. Excessive smoke is usually because of jetting being too rich, not the amount of oil.

    Sorry typo
    Meant 32:1
    So I'll go to 40:1 and see if there is a diff in the fumigation cloud.
    If I'm jetted to large it doesn't seem to stumble much.
