Service manuals/Burning oil, 800 Sportsman

Hello all :wave:

I’m currently looking for a service manual for my 2009 Sportsman 800 Touring.
The quad is currently burning oil and I need the torque specs for the entire top end before I go ripping it apart.
If anyone has a copy that would be great.
Also is there a general problem with these engines burning oil? (I see i’m not the only one) and also is there a set cause for it?
Any info would be great,

Thanks ahead of time,
Ian
