Default Base Gasket removal

Got the piston cylinder off. Trying to figure out the best method to remove the base gasket without scratching the sealing face. The dealer said they use new razor blades. Anyone got a better method. Any kind of chemical to soften it up. This one is black and doesn't feel like paper.
Thanks in advance.

Sandblast it off

Seriously. Those stock gaskets are a bitch!

You can spray on some gasket removing stuff. You can carefully go at it with a razor blade. You could try some Goof Off. I haven't tried it but heard it softens it up and makes razor process a little easier. I use a razor and follow with fine grit sand paper. Keep the case bores stuffed good with towels. And make sure you get all the gasket off (all around studs) or you will have sealing issues.

Thanks,
The stock gaskets are thicker than the paper gaskets the dealer gave me. Why the different thickness? And does it make a difference with anything (compression?)?

Mine came stock with the paper base gaskets but that was back in 2000. Any time you change the thickness of the base gasket you change the squish area and compression. Do you have any idea what the difference in thickness is between the two gaskets? Whatever that is is how much squish would be reduced. Then you could calculate the corrected compression ratio. I doubt on a stock application it would affect either enough to make a difference.

I've tried the spray on stuff, doesn't work on well on base gaskets. I had to do multiple applications and I still scratched the hell out of the surface too. Not enough to leak, but it's scratched. Didn't leak anyway.

take a copper tube (brakeline sized) and hammer one end flat, then file down a bevel on the flattened side nice and sharp. it won't stay sharp but you keep dressing it as needed.

you can wrap the other end with tape to protect your palm while using your new gasket scraper, and the copper is soft enuff to not damage the case.

I use razor blades and then kerosene to clean it. Takes patience.

this is a way old thread but I just wanted to add that of all the work I have done so far on the top end...base gasket removal is the worst part of the entire project.....gasket remover from the carzone store softened it up a little but you have to continually apply it and let it sit...scrape, then more gasket remover and repeat and repeat and repeat!!! Totally SUCKS!!! but after 2 days and hours of time..I am almost done
