    Hey does anyone have some good tips for removing old gaskets?

    I am struggling to remove the old clutch cover gasket from my 2006 DR650. 2 hours of scraping with a razor blade and still only halfway there....

    I always used a dull chisel, I gouged the case less.

    I use paint stripper applied by acid brush. Be very careful as it's nasty,nasty stuff. Have some water close by and wear gloves, eye protection. Apply and let sit for 15-30 minutes and scrape with razor blade. Tough old gaskets may require 2 or 3 tries.

    Cheers, How did you stop the paint stripper from removing the paint on the case cover? Or is it easiest just to do a quick repaint afterwards....

    Goo Gone it for two hours or so then scrape it with a putty knife.

    Wrenching for over 25 years. Bought one of these heads for my small air powered angle die grinder. Where was this thing for the last 25 years? Bought it off of the Matco truck for around $25, and it would be a bargain at $100. Eats right through gaskets and then buffs the surface spotless without eating into the aluminum.

    I bought Loctite spray on dedicated gasket remover that worked good on some pretty stubborn gaskets, sometimes I had to respray a few times but was pretty painless.

    That's a 3M Roloc Bristle Disc.

    It's made of a rubberish plasticish stuff with embedded abrasives.

    It is indeed the cat's ass for removing gaskets without damaging aluminum. The only way to fly.

    I only have the green one. But it is the shiznit. Leaves gasket surfaces like new. I will never scrape again with a blade.

    oh that stuff works, and damned good too!

    Just DO NOT let it get on anything you don't want paint falling off of.
    Ever seen that crap Easy Off Oven Cleaner.....that is what it will do to paint.


    I buy more of that stuff for stripping finishes off of parts than as a gasket remover :lol3

    Great input! Thanks for the responses!!

    I might try some aerosol gasket remover and then get one of those bristle discs for next time.

    You've piqued my interest. Forget the gaskets, what would one do to an oxidized aluminum engine case, given what you say about "buffs the surface spotless?" :ear

    I'm in the process of rebuilding a '74 Honda CL450 and ran into the hardest gaskets I've ever encountered. Since I'm doing the work in our basement and my wife has a very sensitive nose I decided to try Citri Strip. I used it to strip paint off our stair case last summer and had some extra lying around. I used an acid brush to apply it. It's not a miricle worker but it doesn't smell like a chemical factory and slowly softens the gasket material so it can be scraped off. The routine is: apply, wait 8-12 hours, scrape, apply, wait 8-12 hours, scrape, repeat as necessary. If your not in a hurry it works just fine.
