Ok I had my bike down for the past few weeks repairing some minor stuff. I changes the oil and when I started it up i noticed that It had white smoke pouring out of the exhaust. Now this might have been my fault as I did put some gas in my bike that was laying aroung in a small container and then relized it might have been mixed gas from a weed eater.LOL ok so I pulled the plug out tonight and noticed that it was a bit dark like a oil or carbon... almost like a 2 stroke that was running rich. So where so i go now? replace the plug and fresh gas? any comments?..Im still so new to 4 strokes but im learning fast.

Sounds like you have pre-mix in your tank. Usually when a four stroke burns oil its blue. White usually indicates headgasket, antifreeze smells somewhat sweet when it burns. However imo you have premixed two stroke gas in yours, as your plug indicates a rich condition. Thats just my 2 cents.

white smoke=water/coolant burning blue = oil black = a rich condition/excess fuel. old fuel could be contaminated, it can absorb water if left open for any length of time

Are there any common causes for Raptors burning oil. (not trying to hijack, just adding to the thread)

Mine burns some oil. I can smell it after riding it hard. Also when I let my friends ride it and watch I see some white (could be blue) from the tailpipe when they shower down on it.

Doesn't really bother me, its an '01 so I figure its seen better days. If its just worn out, I'll just keep riding it till it has no compression and I'll rebuild it. But if its something common and fixable, I'd like to fix it before the oil toasts the rings.
