So I still have some play in the kips rod after replacing the seal. I know motorrad had to replace the rod after performing a pressure test. My question is what did you use to apply/test the pressure?  Is there a certain tool?  Should the piston be at bdc?  How much pressure?  Thanks.

You can buy a tool or you can make one..

Remember to test positive and negative pressure.
Should hold 7lb overnight.
The four stroke engine: That's one stroke for producing power and three for wearing the engine out.

Thanks blaster. You site is great. What is the plug in the pictures for?  The exhaust?

Yes, one plug is for the exhaust, the other plug is for your carb boot.
I think somewhere on KXriders is a pic of Motorrad's complete set up.
IF nobody chimes in I'll see if I can find it after work today.

Looks good.
The only problem I see is there is no negative pressure gauge or am I missing it?

No you're not missing it. I am going to switch the Schafer valve out for a barb and use a mighty vac for the negative.  I wanted to go through the spark plug hole like you did but it seemed a ton more difficult.

So the motor would not even come close to  holding vacuum.   Looks like I'm ordering a new kips center valve

I obviously had to put my head on with the head gasket to pressure test the motor and now since I have to redo the kips valve I had to take the head back off. Did I wreck the gasket?  Are they reusable?  It's a cometic metal gasket. Thanks.

I've reused them with no issue.  But all my stuff is perfectly flat. And lapped together.   So I get away with more.    I ran 3 used gaskets stacked together once.

I have reused mine on occasion but never after running it for a while, but probably could have on a few occasions.

Thanks guys!  I lapped the head and obviously didn't run the motor as it was leaking like crazy. I think ill reuse it. I would imagine the leak down test would also show if there were issues with the head gasket.

 How can a KIPS center valve cause a vacuum/pressure leak?
