Oil Baffle

PostAuthor: Dougiesdad » Thu Apr 17, 2014 7:30 pm

Unfortunately, I have to tear Christina down to replace the rings(along with giving her a LONG deserved scrub down and hopefully a polish). When I pulled the cam chain covers off the oil baffle was on the front cylinder, according to Yamaha and Clymer's manuals, the oil baffle should be on the rear cylinder. Can/Will someone tell me if this is a major issue? The PO did use the proper covers when he put it back together.

Ok....but why would the Clymer's and Yamaha Service Manual say it is on the rear? I can understand the Clymer's manual since it is a multi bike book. But the Yamaha Service Manual is for the 920 J and K models.

there are things in manuals that are wrong.
if the baffle was on the front and your engine is a 920 then this is correct..
i only ASSUME that the 920 has the baffle on the front head is due to it has 1 petcock where the 750 has 2 petcocks and the breather hose will get in the way of the petcock. this is why the 750 has the breather on the rear head. :con: ..........dan

Hi Dan,

Do you know why ?

I have a TR1 (european model of the XV920) and when I disassemble head cylinders I remarked that the oil baffle was only on the front head. But on the "Part List XV1000 1981 (5A8) France" that I have, it is mounted on the rear head cylinder.

Any explanation, opinion, would be interesting.

don't mean to speak for Dan, but generally speaking ...
the ultimate "why" might well need to be referred to the design engineers at Yamaha, unless you could be more specific / less generic in your question.
the more precise the question, the better it is to find a detailed answer.

Yes it is a generall question, not only for Dan.

By why, I mean, to your mind, why do think it is like that, did you have a bad experience with oil baffle mounted at rear while it is normaly mounted at the front ?

Normals question that it will provide an accurate picture of "this thing that many people remarked" / and I remarked on three of my TR1.

if I am understanding correctly, you are referring to the crankcase vent?

if so it was on front cylinder [Gen-II] and I think varied on Gen-I models, I believe it was more about "plumbing" concerns than anything I know of.

either position is equal function.

I've just taken a look at my 1st gen 750 and 920. the 750 vent breather is located in the front #2 cylinder. on the 920R, the breather is located on the rear #1 cylinder. so, my observation is that it all depends on where you vent tube is on the frame of the bike.
