We'll you probably have one of the following issues if not a combination. Bad coil(s) clogged hi jet(s) or piston ring blow by. Does the bike smoke at all. Does it sound like it is bogging down. Does the bike run fine on the rpms below 9000???

Hi Vince,
Just letting you know that you only need to post a question once. It's no problem, but I have deleted your other posts.

hi byte2022, thank you so much for the help..right, she does not smoke,but she does not have thar accelaration that it must have for a Ninja as i had an old gpz 699 ninja that seems to have had twice the power...even if i cruise in 4th gear at fairly low revs and open her up,its live a 50cc power,to your question, she does bog down and also does not start at first press of the button,there is some ugly no name brand slip on exhaust on it and dont know if he set the jets...do you think it could be the jet settings?. i tried on the freeway again today to pull off fast and go over 900 rpm,but no luck and like before,i pull clutch in and she revs to 16000 rpm no problem

we'll hopefully that doesn't mean you have the combination of misfire and piston blow by. Check your oil please. Does it smell gas like at all. Yes the oil. Does it smell like gas. If not you may need to re- sync the carbs as one or more May be overloading the bike. When's the last time you checked your plugs? Never right since you just bought it. I'd check those next and while your there inspect the coils real good for mis color or a powder looking residue. Let me know what you find. Last thing, has it run like this since you got it or did it just start?
