    1995 Polaris SLX 780 smokes a lot - excess oil flow?

    My 1995 SLX smokes a lot. I think it is injecting to much oil.

    Is there an adjustment screw?

    Any help would be appreciated.

    Thanks

    My sl650 is the same way.. I had 3 people ask me if it was alright when I was riding at idle.. I think I'm going to plug off the oil pump and start pre mixing it.. I heard that's the best way to do it

    It will probably smoke more with premix, with it using a higher mix ratio than what you get with the oil pump. Smoke is not a bad thing on a 2 stroke.

    Make sure the linkage is still connected from the carbs to the oil pump, if not it will oil at full potential

    Check that the linkage between oil pump and throttle is actually working. I think your engine has a variable flow rate oil pump. That means as you squeeze the throttle it increases the oil flow.

    At idle the oil pump normally pumps oil very slowly. But if the linkage disconnects the oil pump arm falls back to full oil flow at all times. This is a fail-safe design so the engine always has enough oil. But it will smoke a lot more than when the oil pump to throttle linkage is properly connected.
