sx505 smoking

[505power]

i have a sx 505 quad with about 22hours on it, every time i stall it or it bogs down if im in the wrong gear huge amounts of white smoke comes out of the exhaust and then once you give it a few revs it clears out? has anyone had problem?

I have seen that on bikes with a cracked head or jug, but it also
would force coolant out of your radiator too.

Sounds like it might just be a bunch of raw fuel in the intake.

what about a valve stem or valve seating seal because it only does it on start up?

I don't think valves would cause a cold smoking condition.

First thing I'd do then is :

1) Compression test.

2) Leak down test (is your quad still under warranty?).

no mate its not under warrenty, i cant see it being compression because it still goes hard, hasnt lost no power at all and it runs smooth?
