Supercharged
Hey Martin I on very rare occasions get that tiny intake backfire as well but I think it's the TPS setting myself, I am going to try a couple of things before I confirm. It hasn't caused me any problems and it only does it 1 or twice during a ride and only if I blip the throttle.
Pretty much identical issue for me @John Miller Tends to be when bike hot too when blipping the throttle or when quick on the throttle to pull away
