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.

Perfect kit.

I've used these kits on every bike I've had. Perfect fit & good quality. A must have when doing a 2 stroke top end.

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.
