What are the thoughts on using a copper cylinder base gasket on a 78 gs 1000? I know we all agree that the OEM are the best as a paper/ fiber type , but I have never heard argument's for or against a copper one. Thoughts from the experienced please ?;)
 
I use copper base gaskets on mine because with the heavy duty studs and 40-50lb torque, the paper ones get squished. Copper base gaskets are also made in several thinknesses from .005 to .020 or so to tune your deck height.
Copper gaskets need a sealer put on them like gasgscinch or permatex.
For a stock bike I would use a regular gasket.

OK question answered.sort of.

"Copper is for race motors that come apart often. Ray. "

Is there a reason you wouldn't use one on a street bike? Are they more pron to leaks? or is it just a cost issue?
 
I use copper and they do tend to leak a little.
I'd use OEM on a stock motor.
 
I actually used gasgacinch and it weeps a little. I am totally happy with them. (copper head and base gaskets)

OK thanks!
I'm surprised because I was under the impression that they would not leak with Gasgacinch. I must add that I have not used mine yet.
Thanks!
