That's a 250 head. I don't think they are the same. Even the XL and XR heads are not the same for the 350. There is a brand new XL350 head on ebay - it might be the only one in the world for that matter. But it's almost $400. I have hours of time into this so far, but only a few hundred bucks. There's only so much I can justify spending on a bike that, if in good running shape, would be worth no more than $1200-1500, and is worth more in parts. I'll pull the head tomorrow and see what's up.
