when the engine is running i could feel the exhaust pressure coming out of the hole, just like when you put your hand behind the exhaust pipe.

Well you could just plug it but I would be worried that it would fall out again!Maybe just plug it till you can get a REAL plug.

I got to looking and the actual decomp. plug is there. The retaining bolt that goes through the "SIDE" of the head is whats missing. I have put in a bolt to plug it and my bike went back to normal. With the plug missing the bike had a very very bad bog and knocked the power down some. and was a bit@h to start. Now no bog,1 kick starts, and wheelies that never end. Who would have thought.....................
