Nope, you shouldn't assume...
OEM piston ring sets are still available for the GS850.
Most online fiches are a little screwed up, but the standard size rings are part number 12140-45121 and are available for $25 - $30 per set (one set fits one piston) from your favorite source for Suzuki parts. They're in the crankshaft fiche for some reason.
If you remove the pistons, make sure you install new circlips.Last edited by bwringer; 08-10-2013, 07:54 AM.1983 GS850G, Cosmos Blue.

Use the Permatex copper aerosol, coat both sides- I use it on all engine gaskets and have never had one fail.Comment

Suzuki gaskets are designed to go on dry. They knew what they were doing, even back then.Comment

On the off chance one has to crack a case or cover open, how easy is it to remove the gasket once sprayed with the Permatex Copper?Originally posted by Badooka View Post
Does it adhere to the metal?
Is it a thin layer that creates a "dry" skin, or a thicker layer that oozes when compressed?'83 GS650G

I'll admit to using copper coat on both sides of a base gasket. There are two camps on this. Most of the controversy probably stems from comparing apples to oranges. A very well machined surface does not need anything to fill in the grooves. On a rougher surface some added filler is nice and probably warranted.
I remember researching surface smoothness specs for an MLS gasket and the best that I could come up with is that the surface needed to be "pretty". In other words I was unsuccessful in determining a spec to give to a machinist.
I have been using composite head gaskets and I think I have put them on dry.

I have replaced head and base gaskets and have never used any kind of sealant. None of them leaked.Komorebi-The light filtering through the trees.

+1, Done it twice dry with OEM gaskets top and bottom and no leaks...Comment

It's worth the effort and peace of mind to use the Permatex, especially on 7-8K dollar motors. It goes on wet and cures dry.
It will aid in the removal of the gaskets. I build a lot of motors. Not just blowing smoke.
It also gives extra integrity to the gasket making it last longer and seal better.Comment

It goes on wet and will dry to the touch- will not ooze-Originally posted by BigD_83 View Post
It's worth the money and then some. Unless one likes tearing into heads and the like to chase leaks.Comment
