Durability 4/5 Ease of Installation 5/5 Performance 4/5 Power 4/5

I have used Cometic Top End Gasket Kits dozens of times when rebuilding the top end of our two-stroke race bikes. All the kits arrived with all the proper and necessary gaskets to get the job done. We have not lost a single head or base gasket since we started using Cometic.

Exact fit

Perfect fit for my 89 RM125. As always great quality.

Top end gasket kit for 1985 KX250

Only reason i gave any stars was because the head gasket worked and the oem head gasket cost more than the whole kit. Bad thing was that my cylinder base gasket didn't fit right and i had to cut out bolt holes to make it fit. Also had to cut a hole for the exhaust valve operating rod. I am going to go with the oem base gasket which is $7 so I'm ok with it just wish I'd have known because now i have to tear it right back down to put a good gasket in it.

Well made

Gaskets fit well, They must of updated their product from the look of some of these older reviews. Fitment was good and it seemed to be better than stock.

Gaskets

Over all great, only issue I had was one of the gaskets was bent and I had to install the old one for now. Other then that, I will always use this gasket set.

Crf50 kit

Says its a top end kit but it only came with the cylinder gasket and head gasket. No cam cover , no valve cover . It seems to be doing its job but i would not have bought this "kit" had i known

Head and cylinder gasket in the kit were wrong

Physically it appeared the gaskets would have fit over the studs but the cylinder to case gasket did not incorporate a port coming from the case into the bottom of the cylinder. I don't know for sure but assume this port is the oil passage port that provides lubrication to the cam and valve train in the head. Rather than gamble and guess i bought OEM Honda Gaskets...

Cometic gasket set

I've only used these and OEM. I've had one head gasket go bad in 20 years however these do bump your compression up slightly :)

The gasket set was great and doesn't need to be scraped off when removing so replacement is easy.

Half of the gaskets were right, half were wrong.

The base gasket was the only gasket that fit. The power valve gaskets weren't even close to being the right size or shape.

Great way to waste a ton of coolant!

Bought this for my 2006 kx450f and started leaking really bad and had a pool of coolant under my bike before the bike even warmed up! Go OEM all the way.

Not satisfeid

I purchased this kit and did not read the small print. Picture shows all gaskets as you would expect to get when you have a part that is labeled as a KIT and not just a base and head gasket not only was I out the time but also the freight to send it back to MotoSport. The return process was easy!! Seems they would not ask you to review a part that was sent back.

A: Different gaskets will give a different SQUISH. Using the Manufactures Tools you can set the squish based on base gasket thickness. Husqvarna or KTM tools will work. Check your Service manual for Tool part numbers.
