QUESTION: did the ‘73 TX650 actually have one of those baffles?
I know that the later bikes do - but this is a fairly early 256 engine model......

The head off of my XS2 did not have that baffle when I pulled it off, and I’m quite certain I was the first one in there since the factory built it. I reassembled it with out it.

Thanks for the info. I must admit that I was having trouble believing that it was a vital part.Yamaha did get complaints from some owners about too much oil or oil vapor coming out of the breather on the earlier models. They took various steps over the years to try and reduce it. This baffle was probably one of them.
I cover the whole gasket.Buy all the way around the gasket do you mean all the way around the perimeter of the cam chain opening, or more than that?
A dab at the front and rear might work just fine. Covering the whole thing is prolly about 50 cents worth of sealant. Seems pretty cheap insurance in my opinion. Your engine to do as you please, but I'm not sure I understand why you want to scrimp on sealant?I'm not going to cover the whole gasket with ThreeBond, I can understand doing that if you are using spray copper. Maybe somebody will chime in on using a little dab at the front and rear of the timing chain tunnel where oil fling is pronounced.
