Please forgive me if I'm being dim but I'm quite new to this. I have an 05 bandit and as I move up through the revs I get a sudden burst of acceleration between 3000-4500 revs. Once I'm past that point it calms down and accelerate smoothly again until I change gear, then it happens again.
There is a very small hole I'm the exhaust which is going to be sorted this week, could this be the problem or am I looking for something else?
Any assistance would be greatly received.
