need an I.D. on this motor

[homebrew13]

i just traded my 85 350X for this 84 250R. it's supposed to have a 300 or 310 kit on it. it has a 4+ swingarm and an unknown pipe(i'm assuming its a FMF from the sticker on swingarm). heres a few pics. just want to know if thats a stock head or not. looks differant to me.

Yes that is the Hondaline 300cc kit. Both the head and cylinder are different then stock with the hondaline kit.

what is "hondaline" is that the factory racing stuff vs stocker stuff?
