Reed valve

By   on  Verified Purchaser

Description didn't say reed valve gasket was not included.


Nice gaskets

By   on  Verified Purchaser

These look to be very high-quality gaskets. The thicker, coated head gasket should be great for a rebuild where the mating surfaces might not be absolutely perfect anymore. It's a little expensive, but you get what you pay for with parts. I haven't been let down yet by using high-quality parts and correct torque specs, etc.

Seems like a quality kit...great price


Top quality

By   on  Verified Purchaser

So far so good, last gasket kit was a lot cheaper in quality and head gasket blew right away!


Good

Good gasket set. Thanks


Great kit

By   on  Verified Purchaser

Great kit, everything fit well. The only issue I had is the valve stem seals were all in the same bag, with no indication of which seal was for intake, and which is for exhaust. From the factory it all came with the same seal, but this brand had two slightly different styles.


It's all there

By   on  Verified Purchaser

I bought this this kit because it has all the copper washers, multiple cylinder base gaskets for assured deck height, reed cage and intake gaskets are also included. I wish it had power valve o-rings but it does come with a power valve gasket as well.

Much better than the one Wiseco sends with their kits and is a great seal. I highly recommend these for any top end work.

Answer Question

Does this set include valve seals

Yes, all Athena top end gasket kits for four-stroke motorcycles include valve stem seals. There's no need to purchase those separately - it's all in the kit!

By Staff
Answer Question

does it include a base gasket and head gasket

All of Athena's top end gasket kits include a cylinder head and a cylinder base gasket. In the case that your machine's OEM head gasket is actually of an O-ring design, that's what will be included in the kit. Athena gasket kits are designed to be of the same shape and size as the stock gaskets and O-rings for the machine you select from our fit guide.

Answer Question

I have a 1985 Honda TRX125. Why would you call it a top end gasket kit if it does not have a cylinder head or base gasket? Does it have them or not?

Each top end gasket kit for the 1985 TRX125 certainly does include the cylinder head and cylinder base gaskets. There's no need to purchase another TRX125 cylinder head gasket kit - everything you need is in the box!

Answer Question
