    SL 780 oil pump question

    Got a SL 780 recently which smokes a lot. Checked the oil pump adjustment and the linkage length is ok. What bothers me is that the Clymer manual states that if the linkage comes off by accident, the pump will go to max, which is anti-clockwise viewed from starboard side due to the spring.

    The linkage however rotates the pump CLOCKWISE as the throttle opens, so actually giving less oil ? Can anyone help clear the confusion please ? What is the correct position for the links to the pumps shaft and why is there no idle alignment mark ?

    Thanks !

    It looks as though you're in the wrong position and running full open now, which would explain the excessive smoke. Unhook the arm and swing it counterclockwise from 11:00 (where it is now) and reattach the rod. (final adjustment will be determined by your throttle setting)

    More throttle more oil! less at Idle is what the pump should do! IMHO
    Most of use have dumped the oil pump in favor of mixing our own into the fuel the benefit is not having a pump or line failure and ruining your motor! Z

    I was commenting on his thought of less oil at top speed! I don't know the position of the arm from a funny looking cat I dumped my pump before I ever ran my ski! Z

    Welcome to the Hulk. Most on here have removed the oil pump in favor of going premix for piece of mind. Maybe try CrazyA's idea of rotating the arm?

    Thanks guys !

    Thanks for all the help, it seems the arm was rotated too far clockwise. In the position of Beerdart's pic I can now see a mark on the arm aligning with the body at idle. I like the idea of premix and have decided to go that route, one thing less to worry about. Thanks again.

    Good choice! you'll want 40to1 get a nice mixing cup and a dedicated fuel can and always add the oil when you fill it up! never wait till later if you know what I mean? so you'll be needing an oil pump block off kit also! Z
