Bandit problems

Hi! If you’ve solved a problem……….comes another …..sighs. You’ve helped me really well a short time ago and hope you can help me a little bit this time too. My 600s bandit does when I give abruptly gas, for about 1-2 sec. briefly bag together and after that it goes off powerfully. Sometimes I think this is only the case when it’s warm. But can also fool me, because when it’s cold I drive it comfortably warm before I turn a little more on the gas ! 😉 New spark plugs are in it. Jump in and so it actually runs really great !!!! Could the air filter possibly be to blame ? Because it really should be changed. I also recently installed a gasoline filter. The bandit had no before. Could this lead to problems ? I don’t think further,….sigh.
