Title: Which Gaskets - generally speaking
Post by: EZRIDN on February 12, 2020, 06:42:06 PM

I really couldn't find any threads where this has been talked about.....what is the consensus when it comes to replacement gaskets?  Stick with H-D or go aftermarket?  if aftermarket, what brands/suppliers are recommended?   I'm talking about outer/inner primary cover, transmission, timing cover, rockers, etc.

You’ll probably get lots of opinions (Cometic and S&S seem to be very popular) but I have always stuck with H-D gaskets, mainly due to the convenience of having a dealership near my work, and I have never had any problems.

We always use Cometic.

FWIW. The Cometic water cooled head gaskets can also be used on the NON-WATERCOOLED engines with no problems.

Any thoughts on James gaskets?   

Also, anyone have any inside track on who is the gasket supplier to H-D?

We use Cometic and sometimes James.  Only Harley gasket used is upper and lower rocker box gaskets.

I always use either Harley or Cometic.

James is good also.

Agree. I've had cometic rocker cover gaskets not work so well. harley only for the rockers. I don't use James much. Cometic or Harley for me. For head gaskets Cometic MLS.

You end up using a mix of everything if you do enough engine combinations

Cyco head gaskets get mixed in often
