The attached photo shows the left side crossover pipe that I would like to remove to change the o-rings. Now that I have the bolts out, can I just gently nudge that 90° fitting outboard, i.e. away from the bike with a rubber mallet? I've not done this before and I don't want to bugger it up. Thanks.

It should just wiggle out Pete. If not, a few light taps should free it.

It is probably stuck pretty tight to the head but a light tap should break it loose. Be sure to lube the new o-rings with vaseline to get them to slip in without damage.

Yeah, pop it up, then out.
And a mallet is fine so long as you don't knock it for a home run.
Some light taps on the sides and lever it up with a screwdriver if need be.
A good mallet-tap should get it though.
Depends on if someone previous used glue or not.

Coated with RTV Black works. Done it myself on intake gaskets with my manifold. Ran it a few months that way. I was out of gaskets and had to do somethig. Actually, it was a Gerber Barley cereal box.

Not yet -- haven't had a chance to get back to the garage yet. I'll get it tomorrow morning.

Thanks to you all for your assistance. I'll let you know how it goes.

Crossover pipes are off.

Got 'em off. There was a small problem in that the 90° elbow gaskets were stuck and had to be pried off, but with a little gasket remover and maybe a razor blade they'll clean right up. Thanks again for the help, guys.

Replacement gaskets came with the o-rings, so I should be able to put it together tomorrow. Here's where I got the o-ring/gasket kit, in case anyone is interested. (glhonda sent me the link.)

Gasket Removal Made Easy

Well, maybe not easy, but easier at least. On the 90° elbow gaskets I tried using a razor blade and gasket remover (Permatex using their instructions), which didn't work at all; then I tried brake cleaner, letting it soak for 10 minutes and could get a little of it off. Same thing with paint thinner.

And then I saw my spray can of paint stripper. BINGO! After about two minutes of soaking, it just wiped right off with a paper towel. Didn't even need the razor blade.

I haven't searched the site to see if this is common practice, but it sure worked for me.

Those old gaskets can hold quite well. I ran into the same problem with those cross over tubes when I changed my head gaskets. Paint stripper would worry me for fear of its intended purpose: stripping paint from the engine block. That is probably a case where "less is more."

If anyone knows of a easy way to get the paint off of those things, let me know please. I need an easier way. Anyone accidentally remove the paint with a particular chemical?

Agreed, less is better. On the engine block side, I backed up the area with a folded paper towel and sprayed very carefully. There was a little over-spray which I immediately wiped off with a clean towel - no harm done. And I did use a razor blade on the engine block half of the old gasket.

Yep, oven cleaner.
