Well mine only has around 200 miles on it yet.
I try to clean it. But the bottom will get nasty because I don't lay on the ground to clean it.
I just got the oil line back on and about to crank it up.

So there is the tin that in the way mostly, right side (1,2) is got the grime, but I looked at the left side (3,4) and 4 was cleaner than 3, plus hard to get back and get the angle I need to see that area.
So I did not snap a pic, probably should, but at that section of head enters the case, are they flat surfaces (case & head) or is there a lip on the cylinder that mates with the case ?
I ask because I can not really see a shim, but it does not look like the cylinder mates flat against the case, a fine edge of the cylinder can be seen and I slide a .025 gauge along the case and into that space, .030 would not fit.
I will take the pic, hard for me to see a difference when I do not know what I am really looking for, maybe others will see it.
back in a flash, Let it roar Rex.

Ok well.....that does narrow things down a bit.
No huge shims. Most non stocks do require shims and/or custom machine work.
It does not look cut for 94mm bore. There is additional machine work involved in that.
It does look like the step the cylinder sits on is very small.
Possibly 90.5 to 92 bore cut.
So assuming it is 76 stroke then....
For a no to minimal shim it would have to be extra short rod (not common) or B pin height pistons and a long rod.
This does give me some idea of what it maybe, if one ever had to pull a head off than they could measure the cylinder bore. Eventually with all the data collected one might get real close to figuring it out with out cracking open the case, but still one should wait on buying parts for the rebuild until they know what they have inside the case.
A bit chilly still, but afternoons are nicer, so the sun is pushing me to ride, so not much longer I hope before I can do it.
I was told that if I pulled the oil pump out that I than could see the bolt pattern of the cam. 3 rivet or 4 , something like this, which I believe the 110 cam is the 3 rivet, or bolt style. I will get the terminology more correct soon.
I guess one should check for wear in the oil pump occasionally, and a few other things can be noted to help identify the volume output of the pump, well is stock or more ?
I want to ride, not play mechanic all summer.
Ok.....yes if you pull the oil pump out of the case you can identify a few things about the cam.
Most cams are stamped on that end.
And you can see if it is flat and 3 bolt or dished and 4 bolt.
Almost all the hot rod stuff is flat 3 bolt.
The oil pump body does not have to come out of the case to identify the pump.
The sizing terminology is the width of the gears. Diameter is the same the width is what changes. You can just take off the cover and pull out a gear. Nothing holds it there, it is trapped by the cover.
The pump could wear on the outside diameter and or score up around the outside. But that is more rare unless some metal has been pumped through.
The main wear is end play. We are only talking a couple thousand extra end play and hot idle pressure will be low.
I see pumps put on with a thick gasket or gobs of silicone. That just kills the pressure.
You want the pump gear smooth flush to the body and a super thin paper gasket on the cover to make the end play.
I asked because I wanted to see if this was some correct info, and is the info I get worth the effort.
I think it would be worth the effort to see what condition the oil pump is in, plus you said "gooped up orange sealer" well that is what was done to this one. Looks like most was used between the case and pump, not much if any between pump and cover plate.
A nice clean up job is in order in this area, for sure, so no real wasted time doing it. At least I can put it back together correctly and gain a little bit more knowledge about this engine.
Thanks for the reply.
