Not bad

After installing this gasket I noticed a big difference in top end. Will use it again next year!

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

Carl Verified Purchaser
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.

Missing parts

Kit was missing valve seals and oring for bottom of cylinder for an 02 400ex. I understand that the pic is a "stock" pic but they're both in the picture. Plus every other company's top end kit that ive used (moose tusk, no name, oem) includes both of these items! Personally won't buy again.

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.
