i have some gasket material that says "rubberized fiber" and on the website of the company it says it withstands up to 350 degrees. is this ok to make a valve cover gasket or should i get a different kind. it 1/32 inch thick.
 
Sounds about right. Measure the thickness and compare to the stock gasket to be sure. A piece of sharpened tubing works well to cut out the bolt holes; punch them through with a hammer.

Good luck and share a photo or two of your process.

I made a float bowl gasket once...works fine but took a ton of time.

A another good tip for punching those holes EASILY is to just use a hole puncher. Don't know if you have one or not but I used one we had laying around and it worked beautifully. I just made my own valve cover gasket and it looks pretty good
 
Mr. catbed,

From what I've read in this forum, the oil temperature should stay below 300 degrees (normal is about 200-250 degrees). I don't have an oil temperature gauge on my bike. If you'd care to look, there is a valve cover gasket fabrication guide on my little website. Just click the link in my sig.

Thank you for your indulgence,

BassCliff

That last hole was there for some other carb model, my bike did not need it cut out so I stopped.

That material will work fine, but crikey, that sounds like it'll take ages.

Might I suggest....?

Is there some good reason that hours of pecking away for possibly dubious results is better than spending a few bucks? Or is that a personal question?

Catbed,

What bike is the gasket for? It seems the RealGaskets work better on the 8 valve motors because they have more surface area. I had a RealGasket on my '83 1100E (16 valve). It squirted out twice and started leaking. I was very careful to have perfectly dry surfaces when I installed the RealGasket and used an inch-pound torque wrench to get the proper torque. I replaced it with a stock gasket and haven't had any problems since. One trick with the stock gasket is to put a thin layer of grease on both sides of the gasket before installing it. This will save you a lot of time and trouble scraping the surfaces next time you remove the valve cover. I have an old valve cover gasket in my garage that was on the bike for years. I had applied grease to it when I installed it and it came off with no residue whatsoever. I could probably use it again if necessary. The OEM gaskets or aftermarket replacements are readily available and aren't very expensive.

Thanks,
Joe
 
Oh yeah -- forgot to mention that the Realgaskets are sometimes a problem on the 16V engines.

The sealing surfaces are wider and less intricate on the 8V engines, so the RealGaskets work beautifully. And truth be told, sometimes I've reinstalled a RealGasket on a GS850 when the surfaces aren't surgically clean :shock: , and never had a problem.

One interesting tidbit is that I installed a new RealGasket last week on a GS850 engine I was rebuilding, and they seem to be made of a much stiffer silicone material nowadays. Don't know what this means, exactly.
 
Judging from some other posts, "catbed" is working on a GS850G, year unknown.

So a RealGasket would be The Right Stuff.
