Base gasket matching

[marrcel]

After matching the case to the barrels i noticed an asymmetrical print. I compared the orange gaskets from before matching the case with the one piece gasket which i used after case matching.
The Inner transfer side of the LH barrel is way more inwards then the RH. I did not change the barrel transfer print at all.

Making the transfers of the barrels the same seems ideal to me.
How did you guys cope with this?

I place the base gasket onto the engine .. then using a fresh #11 exacto blade run it inside the case casting opening.
This easily trims the gasket to the actual metal casting.
Always iffy to cut down/trim these gaskets because of the possibility of a subsequent leak (if something gets bungled )
Leaks here are Bad news,

Thats a useful tip!

You can do a leak down test after engine assembly to make sure there are no major leaks.

May be i did formulated my question wrong.
I matched my case to the barrels. And i noticed that the print or shape of the transfers was not symmetrical.
May be a wrong or flatned stut on one of the casings thread end??? Or should the barrels be shaped evenly also? Do you guys trim the barrel transfers? Or just only the case?

Btw i do pressure tests. But always the inlets or pv leaked. I always silicone the inlet gaskets and use better clamps on the balance pipe.
The base gaskets do leak only if i forget to retorck after a few 100mls. Keep it thight.

You should use Yamabond or Threebond on the inlets and gaskets and silicone can get affected by the petrol.

I think what you are asking is if you should match the transfers so they are the same from side to side. If you want to get it as accurate as possible, yes you can do this. It will not make a massive difference, but every little helps :-)
