Didn't include head gasket...

New top end kit went well until i went to put the head on only to realize that it didn't come with a gasket for the head. What a headache this store is. have had many issues with them in the past for shipping wrong parts for wrong bikes.

Does not fit 1984/1985 xr200r motor

Despite the fit guide saying it would fit, the gasket fit does not fit the four valve 1984/1985 xr200r motor.

Great kit.

I needed a new seal and this did the job. The kit fit perfectly in my KTM and was easy to install. You can find the seal alone much cheaper, but it doesn't include the O-ring or other parts that are needed to rebuild the countershaft seal correctly. I have used this kit on two of my bikes and they haven't leaked yet.
