Head Oil Orifice

#1

Post by Wingingit2 »

Does anyone know if the oil orifice in the head of the four cylinder Wings is the same? The part number changes for the 1200's. I may have mixed up 1100 & 1200 parts or lost one. They all use the same o-rings. I don't want to screw up the oiling in my 1200 project. Or maybe someone can measure the hole diameter and overall length for a 1200 orifice???

Thanks for any help in advance

The 1200 has a larger inner diameter, so it should flow more oil. I compared the 1000 and 1200's on my hybrid version- 1000 heads on a 1200 block. I would get the right ones. They might be able to be drilled out.

The 1200 has hydraulic valves right? I would think that having the right size orifice is critical in that case.

As best as my measurements showed, the outer dimensions were the same and as mentioned orings are the same. I was just looking at my old post on this and the pics are gone now, but the 1000 had a set of crossdrilled holes in them also.

Nice Pic's. The one's I have with crossed drilled holes have the smaller orifice. Are you positive the 1000's have the cross drilled holes?? I have both styles.

Yes. As Whiskerfish mentioned, the 1200 had hydraulic valves and probably needed the additional oil flow. I have 1000 heads on my 1200 and I think it gets plenty of oil. I can't vouch for 1100 heads, but if the part numbers are the same---

How does that work 1000 heads on a 1200? any different jetting or timing involved? Are you using 1000 oil orifices?

Yes. A few changes needed, biggest being valve reliefs on the pistons. I love it. Is it better than a stock??? Gotta adjust valves every several thousand. I haven't ridden a stocker to compare. Using 1200 carbs, it ran good with the 1000 heads(77). Using 77's required some tweaks. Read Schizoid build. You'll see --- I don't know what I'm talking about, but guys here get me back in line.
