    I just bought a 2012 Speedmaster with only 1089 miles on it and at Idle and when deaccelerating it pops very loudly out the exhaust on the left side of the engine only I changed out both plugs yesterday and the left was much darker brown than the other which looked very normal . I think I may have a bad injector but the bike runs good out on the road , It sound like it is starving for fuel at Idle , I am kinda new to fuel injected Triumphs and looking for help.

    Sounds like a small leak in the exhaust near the headers. That’s the sound they usually make.
