Does fuel get into the crankcase?

[ullose272]

How is the engine on the 2020 designed? Does any fuel get into the crankcase? I was thinking about starting to premix some oil in the tank, but dont know that it would help if its not getting into the crank case

not with this motor. fuel is direct injected above the ring land. this is why the motor can run soo lean on oil. you have no fuel washing oil out of the bottom end so it only leaves under air flow with no fuel mix.
the only way to turn up the oil pump is with a programmer like torq link

That is what i thought. Thanks.

The 2020 injects fuel into the boost port and the 18-19 above the piston and below the piston as the piston has a oval in the side of it

They obviously kept the direct oiling to bottom end bearings then?? Or is the “splash” to the wrist pin all it sees down low?

Same basic design that polaris has used for years. how do they oil the wrist pin?

That right there instills confidence in those trying to figure out what sled will be their next.
