I had the same problem working on my buddy's bike last week. We just put the 88SE motor on and it was popping like crazy even with the exhaust ring. We found out the problem was the SE head was longer and when we tighten the muffler at the back of the frame, it pulled the header a little and wouldn't allow it to seat. We drilled out the hole on the muffler mount to elongate the hole. We tightened the header down first and then made sure the muffler mount lined up and tightened it. Problem solved.
