My streetfighter does this if it's warm. It has the termi slip on exhaust, but it seems to be normal and definitely did become more pronounced over time.
I love it when it does
Will do that under some railway bridges!!! Thanks I'm 10!Applying the tiniest bit of throttle, like just "pressure" and not actual twist, when slowing down will give you lots of extra little pops and burbles, which I'd assume comes at the cost of slightly less fuel efficiency since you are injecting a little fuel. Not sure if it's a good or bad idea (probably not good), but I catch myself doing it every once and a while (because sometimes I'm a 13 year old inside).
