About Cometic

Gasket
Working fine was for my brother's bike
Works Fine at a lower cost
I usually have an OEM from Harley Davidson, I have used this twice on my 04 Electraglide, no leaks or issues. At a much lower price.
A mediocre gasket
I didn’t use this gasket after removing the derby and seeing the Harley gasket that I removed. No comparison in quality. I ended up going to the local dealer and bought an O.E. gasket.
A good buy
The gasket fit nicely and no leaks so far . The fitment was spot on .
There is nothing on them indicating they are actually Cometic gaskets. Are they Substitutes?
