Problem after first service

[BikerBoy]

On riding home, I noticed a few issues not evident before the service.
There was a constant popping/backfiring through the cans on overrun, idle speed was erratic & there was a definate hesitation/fluffiness at small throttle openings.

I've just gone through a very similar thing. I've only just 10min ago changed the mapping on mine and it seems heaps better but still yet to do some proper tests with the data logger.

There's quite a few knowledgeable guys in the forum so they may be able to give some better advice.
