I have a monsoon 90cc. I have what appears to be the original owners manual with it. The Vin #'s match in the book and the quad. It says W2200. The plastics say it 90cc however the manual says 50cc.

Which is it?

 

do you see a 49cc or a higher number stamped somewhere on the engine? whether near the jug/cylinder or on the cast around the sides? whatever number is nearest a round number that is stamped on the engine is what it is. at least that's been my experience.

 

No I don't but I didn't look hard either. I'll pull some more plastic stuff off and look. Thanks.
