Seadoo rotax oil canal mistery

[Nicolini]

I was looking at the rotor housing plate of my rotax 650 seadoo engine and noticed something ,





Why has it the aluminium to put two extra nippels on it as shown in pictures .



Is this for oil or some vacume or presure to manipulate the rotor disc , or other future plans .


Can some one tell me ???

They used the same rotary valve plates on several different engines and at different times in production the oil fittings were moved to different locations, you can call Scooby Doo back and tell him not to show up, this one is solved.

I tought it was something like that is there any profit gained to have them both to extend the life of the rotor and the housing ??

nope, where would you run them from anyway, you would have to split the existing line, the fewer lines you have the fewer you have to break is the way I see it.

Thats true , but i could connect them in factory style to the oil pump and pipeping and lines is something i love and can be done leak free i am wonderring of the oil pump is up to it , i am familiair whit those mikuni,s and have seen them whit 4 lines comming from them but i must confes i am not sure if they where ristricted to keep the pressure up

The oil pump is variable rate , it pumps what it pumps depending on throttle position , if you are going to mess with the oiling system all this is unnecessary run oil injection or don't and run premix..
