I reused the valve cover gaskets for my Bassa too many times. The gaskets got stuck onto the covers and I've had to use multiple applications of gasket remover, which has to be toxic, and do a fair amount of scraping to get them off.
Don't do this!

valve cover gaskets ..... :thewife:

Extreme Guzzi Content! :bow:

Using a heat gun or propane torch, heat the rocker cover until the gasket bubbles and/or smokes. They scrape off easier while "hot".

I have had good luck with the green thicker gaskets, greasing them when first installing. The cheaper black thinner gaskets dont hold up very well for me. Some day I am going to try the silicone gaskets on the Guzzis that need valve adjustment,

What gasket remover did you use. If it’s Permatex gasket remover you might as well used distilled water.
Aircraft paint stripper is what you need to chemically remove dried on gaskets.

It's been said that the cheapest thing on a Guzzi is the nut on the seat. Hmmm, maybe it's the truth. :evil:

Permatex--it's an old can and has the methylene chloride. Still took multiple applications to get the baked on gaskets off. In fairness, those gaskets were probably on the bike for over 50K mi and only seeped a tiny bit.

A long time ago Permatex took methylene chloride out of their formula and not it is truly is as worthless as pouring distilled water on an old gasket hoping it'll dissolve or loosen.
There are still chemical gasket removers out there that contain methylene chloride like 3M gasket chisel. But its expensive and hard to find. Fortunately every auto parts store or Walmart in North America have "Aircraft paint stripper" that contain methylene chloride that eats away in short order old gaskets. The gel is the best spread it on with Q-tip or flux brush and it stays put. Let it sit for a few minutes then wipe the old gasket away. Repeat a time or 2 more for really stubborn baked on pieces.

tried them silicone gaskets once. I didn't like them at all. torque um down swishy out is all I can report.

Trust me, you're MUCH better off with leaky gaskets than inhaling methyl chloride...ain't worth it....

Scotchbrite Roloc in an angle grind.
Got that setup years ago and use it to clean up everything like that.

Zip-Strip paint remover.
Look for the words "Methalyne Chloride" "Toxic" and "Dangerous". That's the one you want.
I coat both sides of each gasket with Never-Seez prior to installation and after each valve check.

You don't torque um down. <shrug> They are used on cheesy stamped metal million dollar aircraft valve covers after carefully straightening them with a peen punch. Snug them up. That's all. Never leak. Last a long time.

I'm sure the fatty foods and alcohol I've consumed are by far and away worse than the 1/2 tsp of methylene chlodide contianing gel I use to remove a set of head gasket residue once every 4 years.

For square fins just get a pair of Valpolini gaskets, Rick and Gordon carry them I think, they’ll last a very, very long time.

Good grief , what are you guys doing to these poor gaskets , I have never had one stuck so bad that a little bit of coaxing wouldn't come off . Of course a little anti seize helps .
