It is a 1998 Sport 400l. Two-stroke automatic.

Any info on what oil, how much, and any others tips (see my original posts) would be greatly appreciated!

 

they say it takes 75 cc at an oil change. but if you over fill it just blows out the vent. I usaully put in about 125-150 cc. and it hasn't put any out the vent line but they it will. it is supposed to be on the knurled area of the dip stick after complete thread in. If you find milky oil in there there is some water in there. If you see this change it again after one ride and see if it is milky again. At the same time as seeing the milky oil check your rad to make sure it is topped up also. As there is possibility that the water came from the seal on the water pump. anyway if you see milky oil again, and you haven't been in deep water. Then there is good chance that the water pump see is on it's way out. fix imediately
And yes they did make 400 two-stroke sportsmans from 94-98. looked old school like a trail boss from the late 80's early 90's

 

Why do you keep asking about oil oil oil.... if u dont know use polaris oil... made by polaris for polaris period

 

hey polaris 500ho guy keep your mouth shut. If you have good advice or a good point to make write it if not be quiet. and as for the guy asking the question go buy a clymer manual, It will be very help ful

 

oh ya sorry rob I would just use 10w-30 in the counter balance and polaris tranny oil in the tranny. but then again it won't blow up in your face with 10-30, If you are in bind before a ride

 

I used 3 oz of Synthetic 10w30 in the counterbalance. The Tranny takes Polaris Chaincase oil, it says a little over 12 oz.

 

how much oil goes in there
