I bought a 2012 pw 50 for my kids and it seems like it isnt running right. It will seem like it is loading up at times and when the throttle is opened up it just seems bogged down? the restrictor plate is out of the exhaust and the oil injection system is still hooked up and running yamalube 2s. Brand new spark plug also. It also seems like it is smoking quite a bit, could the crank seals be bad?

That sounds and looks normal for a PW50. They do this when free revving and over-revving on the stand. Drag the back brake a little when it starts breaking up to simulate a load and it should clear out.

I took the pw out and rode it back and forth for maybe 5 min, the longer I rode it the more it would smoke so that makes me think it's getting to much oil from either the injector or the crank seals leaking? The smoke is white in color so would that point towards the transmission oil leaking through the seals more so than the injection pump over oiling?
