    1994 polaris 750sl question

    i picked up this unit as a trade for a stand up i had
    the guy said that one pistion was bad
    i did a total top end rebuild and it looks like the reason was lack of oil.;
    i been bracking it in for 15 hours and i out on the lake half throttle and all the suden it just dies and after a few it starts up and drive a little and dies over and over. is it overheating ? how can i check the oil pump? should i just unhook the oil pump and mix my oil with gas? what is the mixture ratio for that?
    or is it somthing else i am missing ?

    Stator? My old dirtbike used to run for 10 minutes, then not start for 10-15 min, run for 10, not start over and over. Stator quit after gettin hot.(unrelated vehicle but same issue.)

    thanks for the response i haven't done anything with the carbs i see alot of people doing stuff with the carbs. i thought becasue of the main probem before i did top end it might have to deal with the oil pump. i will take a look at the carbs though

    Polaris oil pumps tend to be reliable. Check all the lines, and check that you actually have oil flow at each feed into the air intakes (not clogged with a bit of dirt).

    Replace the oil filter at some point.

    Carb rebuild seems like the logical next step for your engine.
