Right exhaust popping

[peter]

I have a problem with the right exhaust popping, especially when it gets hot. Valves have been set, timing is set, Cam chain is ok. It is a 1981. Does anyone have any suggestions?

Turn the right mix screw out a bit...richen....better to use larger pilot jets (42.5) like a 45or a 47.5 .......then re-adjust the mix screws properly.........xsjohn
