That link shows a video of the air leak. Any suggestions on how to get rid of that. I have a gasket, spacer, gasket, and the cylinder . The week is in between the cylinder and the crank case.

Looks like you have a ton of surface area for a seal, all u need really need is a couple mm in width to seal. So...im guessing your mating surfaces are uneven.
I doubled up gaskets between the spacer and the cylinder and it's still leaking. Torque down to about 9 ft lb. What I think is happening but I'm not sure is that if you look at the picture there's a little area that's recessed and when I put the spacer on it's sitting on the upper edge so it's not recessed. But at the same time when I doubled up the gaskets it seemed like the gasket filled that space. I'm not sure what to do here
Is the spacer hitting part of the case making it unable to fully compress the bottom gasket?
Yea it is, but it looks like doubled up gasket is filling that gap. I'm going to walk away from this for now because it's frustrating but I'll get back to it in the morning and double check. Plus I don't have any good lighting so pictures are going to come out like crap right now. I'll post some pictures tomorrow
Been one problem after another. I took the case to get bored out. When I picked it up he gave it to me without the bolts in, when I tried it with the bolts The cylinder didn't want to fully go in the case. I had to open up the bolt holes in the cylinder for everything to line up. Not sure if that's what is causing this issue I don't think so though.
Cut the case down where it's hitting or get some thicc gasket paper.
Gaskets will compress too, so even if it works new, they may compress over time and cause issues as well.
I have Shop Craft 37775 9" x 36" x 1/32" Fiber Gasket Material https://a.co/d/e8OsKLb. Not sure how great this is bit it's .79 mm thick.
I cut one test gasket basically the width of that space. I want to see how this works. I don't know if I'm skilled enough to cut the case. But if you look at the pictures if I go down anymore the fins are going to hit. You can also see how the spacer is too wide. Might be able to cut the spacer
I sure wouldn't worry about grinding some off the fins to make it all work .
all this work for a batavus. wild.
After I put the gasket on that I cut, seems like air is making it all the way to the cylinder bolts but now I got a leak in the cylinder bolt. Here's a video.
Should've brougt the spacer to the machinist. Or buy Flat file for $5 and be done in 5mins.
Stick to one post please.
I’ve never seen an application (motor wise)where double gasket is the answer
Usually that means you’ve put one too many on accidentally or your mating surfaces are not making proper contact.
Maybe that’s not the case here but typically you never want to double gasket. The result is usually the seal blowing out (and double gasket on an oil filter on your car the blowout leads to engine seize just for reference)
How about I'll open as many posts as I want. And you mind your business how do you like that

Your first mistake was machining and buying gasket material.
Cereal boxes, beer cans, and rtv never did a man no harm
The “one post” comment wasn’t an attack. It’s just moped army etiquette to open one thread per topic/sale.
Different posts for different topics, I honestly don’t think it was an attack, just standard procedure.
Unfortunately as much traffic as we have there isn’t always enough people on to answer questions in a quick timely manner (maybe the Facebook group may have faster responses?), or the people who may know the answer haven’t logged in in a while.
Unfortunately it doesn’t seem like your question has a clear cut answer so it may take some time
Ended up buying some feltpro gasket paper 1/32 thick. Cut two gaskets. One for top and bottom of the spacer. Seem like this helped a lot. Now I'm getting a leak between the cylinder and the head. And 4 head bolts. The head is countersunk so if I put a 1/32 gasket it's cutting into the compression. Any suggestions. Should I get a piece of 600 grit and run it over the cylinder top?

Yea it's a little frustrating because I have a post open and I get absolutely no response or any input. On top of that who says I don't have a flat file and what am I supposed to file down? Then you look at these post that are so dumb and they get a bunch of responses. There's a post about cryptocurrency and it gets more responses than a regular question that people need help with. Maybe I should put a word like braaap in the title. That should catch the attention of herd minded people. Beeeeehhh beeeeehhh. (edited)
Copper spray gasket for the head
I'm probably going to use the copper spray on my final assembly. For now I just used some permashield sealant. Got it up to 5 psi. 20 minutes later it's Is that acceptable

Meant to say it's at 4.8 20 minutes later
if it was a bubble machine without the sealant and that’s all you changed/added, I wouldn’t think that will work.
The sealing surfaces should be flat enough/mated that they almost seal without any gasket/sealant.
That spacer cannot rest on the part of the case it is currently. That area was not machined for the base of the cylinder and though it may look flat-ish your pic even shows the space it wider on one side than the other. which means the cylinder will be sitting ever so slightly cocked to one side.
Bearings dont like running crooked.
You are gonna have to file that spacer down to sit only on the machined face of the case. If not for the seal, for the sake of your… well everything that moves.

Got this kit from treats. Wish they would tell you this in the description. Here's a pic of the spacer with the cylinder in and no gaskets. And with gasket . The spacing looks pretty even when I get the gasket on. If you guys really think I need to file that down I'll take it to the machine shop. See what he says. The only problem is when I took the cylinder in, It took him about 3 weeks. I called him after The first week, he said he was going to start on it in a few days I waited two more weeks and he never called me even though he had my number. Then I finally called him The third week and he told me it was ready never called me to tell me it was ready. It's like the 2022 effect Where even when you pay somebody to do something it's still a pain in the ass afterwards. When he gave me everything he had it together with no bolts. Soon as I put the bolts on it didn't line up I had to make the holes bigger on the cylinder to get enough play for it to line up
The gasket material will probably take up any weird uneven spots.
If you look at the spacer and it clearly is angled or messed up then yea machine it flat.
If the leak down test is good just run the damn thing.
Copper spray or motoseal on the head will also fill in uneven stuff within reason.
It's just a batavus...
Exactly. You don’t need a machinist. A belt sander or disk or file if you don’t mind getting a tiny little work out. You only need to get this stuff off to match the area below. Use an old gasket as the pattern and mark it. Thicker gasket material would theoretically work but thicker material also crushes down over time and requires more fiddling.

I put the spacer up against a flat metal door which is pretty even and flat . I didn't see any clear uneven surfaces. I also ran it on some 600 grit up against the same surface in a X pattern To me it looks like the gasket fills everything in. My first step when I saw the leak was to try and grind the spacer down. I used a bit on a Dremel and I don't like the way it was coming out. That's when I moved on to a different gasket which seems like it works. I just don't have the skills to precisely machine stuff down. I do have a bunch of files and sandpaper ,all types of stuff that would probably work . That's just one of my weak points I can't do things precisely because my patience is really low. I'm going to try to move forward the way it is. I'll get everything together the best I can with no leaks. Get it started. Hopefully it's still warm enough where I could ride around for a few hours but it's getting colder out by the day. Still have a bit of work before everything is ready to run. I'm going to keep this in mind and If I absolutely have to I will get that spacer fixed. (edited)
dude if you're going to hand mill something, at least use something flatter than a door.
an old glass-topped bathroom scale, for example.
