CDHPOWER 66CC/80CC Cylinder Copper Gasket 2pcs-2 Stroke Engine Motorized Bike

I like

These copper head gaskets are much thinner than the standard aluminum ones. This will allow for a much closer seat for your head and will increase compression in your engine. They are durable and I haven't had any of these copper gaskets blow. Very nice.

These head gaskets worried me at first due to how thin they are but I put one on and my motor actually runs much better now, the regular metal ones always start leaking within 2 weeks, I ride to work and back everyday, but these gaskets haven't shown any signs of blowing out. The head actually sits flat now instead of having a bend, I only torque the head down to 15lbs but it still bends, well not with these ones. All in all I would highly recommend to anyone that had compression issues or blows out head gaskets like I was

Don’t have a compression tester so I can’t say if it has more compression but when turning the wheel by hand it certainly feels like it. Both had some scuffs and scratches but they don’t seem to be an issue, probably damaged in shipping. Rode the bike for a couple hours with no issues. Good upgrade.

Worked great to replace the bent one that came with my 80cc 2 stroke china motor. Came nicely packaged and damage free.

These copper head gaskets looks good, they are as advertise, I recommend them

not really much to say you get 2 quality copper head gaskets for the price of one. very well made CDHPOWER is going to be my first choice in anything I buy from now on thankyou CDH very happy.

This is a copper coated brass This is a copper coated brass head gasket it is not 100% copper as lead to believe I never it does work just remember it's brass not copperhead

Haven't installed one of these yet but they came in great shape and quality looks good.

Works as expected.

Perfect head gasket
