What engine?

ok, cool. I thought it would only need the gasket, but was just making sure.

My fahzah has a 650 with the 650 bpipe and it runs surprisingly good.
Where in washington are ya?
Was that the superjet on craigslist in Wenatchee?

I live in Spokane suva, but I do my riding at twinlakes, id.
I bought the superjet from someone in spokane; I saw it on craigslist the morning it was posted and I jumped on it since it looked in pretty good condition and came with some nice extras, plus I picked it up for pretty cheap. I do need a full pump assembly with drive shaft, I think I will post that in wtb.

I pulled the head off to check for porting today, I do not think porting has been messed with, but I am not sure. Also, Mouthfulloflake said that the O rings in the head might need to be replaced, but there were none. Do I need to get some O rings? If so, can anyone tell be what I need to get?
thanks

That cylinder is definitely ported. Stock 650 exhaust ports are quite a bit more narrow than that.
