Its not right.....
....its gotta be poor fueling;
If its always done it since the pipes and chip were fitted, is probably the chip, - go for a FIM Ultimap and get it setup for your bike. - or get a decent chip for 54mm open pipes.
If its only recently started then it may be blocked fuel filter or blocked air filter.....
