I have discovered that yes, a 16 year-old Ninja 250 still has plenty of power to feel properly quick even with a 300 lb rider. So next time you hear someone say they got a 1000cc sportbike because “I’m too big for a 250”, they are wrong. Granted, I never got it over 40mph because I was wearing a half helmet and a T-shirt (really need to keep a spare at the office)
On another note, this is now the second bike we have “fixed.” Had a stuck float leading to the same engine-full-of-gas situation we saw before. Thankfully we knew how to fix it. Unfortunately, the carbs on the 250 were a pain to get out, since they’re wedged between the airbox and cylinder heads pretty tightly.
