[08Rhino450]

I have an 08 450 Rhino that all of a sudden started smoking like a freight train on start up. After it warms up you cant see any smoke,but after a bout 20 min of riding the oil level is barely touching the stick. I ran a compression test a couple of times and it was 140+ each time, there’s zero blow by coming out of the crank case vent tube and no oil in the air box. It has pretty low miles on it and the only mods are aftermarket CDI, otherwise she’s bone stock. Could it be the head gasket blown putting oil in the cylinder?

*It’s running in the pic warmed up and no smoke.
