Found the problem ,looks like a small rag was in the exhaust,got a wire and poked up in muffler and pulled out part of a rag.I started the bike and the rest of it blew out ,now both sides blow out .
When there is a cross over mostly you'll just lose power. Very aggravating but not harmful to the engine unless you used it that way at high speeds for a long time.
Baffles are made of metal that are inserted into the muffler. I don't think they have packing.
"damn, now where did I put that rag." or a very strong mouse???
