4 stroke
There is no valves as it is a 2-stroke engine .
Polaris four stroke oil is a 0-40w synthetic.
2 stroke-NOT outboard, but the same type such as used in chainsaws
Most 91 polaris 400's are 2-stroke , and there is an oil tank in the front . Make sure the oil is 2-stroke oil for injection .
10-40w
yes ,i think they started in 94 and made them for a few years .
where is the plug on the 400 4x4 ATV to drain the oil? Isn't the 400 a two stroke? No oil in case.
I believe Polaris only made 300 4x4's with an air cooled 2 stroke, which uses injected two stroke oil. There is no oil in the crankcases. Some of the 400LC motors have a small amount of gear oil in a cavity between the recoil and crankcase for the balancer shaft. Your polaris will have a small dipstick on the right side close to the counter shaft sprocket for the transmission.

4-stroke... The 400 is a 2-stroke
