Got my rings and gaskets today.... now i am waiting on my exhaust gasket and cirlip...

Couple questions... just to make sure i ordered the correct things.

1.... are the circlips 17mm?

2.... is a all copper exhaust gasket ok? or should i add some liquid high temp gasket maker to it to make the seal 100%?

They are flat and the surfaces are machined to except the gasket as is. Just my opinion . No mess and no blow out.

The last one I installed was stamped steel. I would take the copper over steel.

When you look at a cyl that has been used the surface will be shiney. You normally scratch this up with a cyl hone in a cross hatch pattern. What this does is to wear in the rings and allow them to seal. In pinch a person could use sand paper but not recommended. I would recommend you take the cyl to a small engine shop or auto machine shop and have them hone it. It is a real simple thing to do, doesn't take long and probably is not going to cost a lot.

this is a hone: www.harborfreight.com/4-inch-engine-cylinder-hone-97164.html there are other types too. Since you have to ask I would have a shop do it, then you will be sure it is right.
