if its doing this on its own, you have an air leak. DO NOT RIDE THIS WAY! GET IT FIXD! My engine blew out cause of this problem and me riding it that way.

How do I find the air leak,and what needs to be done to get it fixed....thanks

Do a search on this board for leak-down tester. Build one. Use it. I did mine when I first assembled my new top end and found a significant leak. It cost me about 1/2 hour of work to fix instead of 100's of $$$ to rebuild again.

what he said^^^^^^^^^^^^^^^^^^^^^

most likely the head nuts, or cylinder base nuts have loosened. check the torque on those, and then check out the reed cage gasket

i'll probably go to home depot and get the stuff to make one....but first i'm contacting the shop and see if they will do anything about it.

Just an FYI: In discussing my break-in with Brandon from Wildcard Racing, he mentioned that he typically uses some sealant on the reed cage assembly because it is a very common leak spot. That's where mine was leaking. I used a SMALL amount of RTV on it and it passed the leak-down after that. I'd say that's a good place to start looking.
