    Hi all, greetings from sunny Granada.
    Just new to the forum. I recently bought a 1986 VF500f. It has been stood for the last 25 years. It had a full service prior to this, so everything is immaculate EXCEPT for the carbs.
    Completely trashed, they had not been emptied , so a real mess inside.
    So I managed to pick up a very clean set of pre 86 carbs - big question will the work on the 86?
    I have replaced the carb to manifold rubbers (2mm bigger than the 86) will the jetting be ok? 86 carbs have main 95, older ones have 90.
    Thanks in advance

    On a stock bike, the stock jetting from a different year will likely be just fine.

    Keep in mind 86 were gravity fed and prior had fuel pumps. The inlet spigot is in a different location and some adaption will be needed.
