Could be caused by bad fuel or an obstruction in the carb. When the tank is dry, try to get a look inside to see if there is rust floating around.
I'd completely drain the tank and floatbowls and refill with fresh gas (87 without ethanol if available) before doing much else.
Look through this section - https://faq.ninja250.org/wiki/Intake
Info on draining the carbs is about half way down. |
ok i will try that as well, 87 is what i have been putting in it btw (not sure if it contains ethanol) however the first time i filled it up i used gas that was for the lawnmower maybe it wasnt 87 lol and i think there is still a little bit of that in the tank
