Yamaha SR500 pinging.?

I have an after market 535cc jug and a SuperTrapp exhaust. The engine pings when under a load especially when its hot. I replaced the spark plug but it made little or no difference. I have a thick stack of plates at the end of the SuperTrapp. A friend

You can TRY raising the needle in the carb one notch/lower the clip on it.
If it's a marginal case of pinging,,that MIGHT richen it up enough cool it off enough to stop the ping.
