Hi,

I am running 2012 ninja 250. Here is this situation, my bike all stock jetting accept slip on muffler. This bike had no problem with hesitate, bogging or never have choke when start. When take off the bike seems to responsive on every gear and spark plug colour is white. Then I want to improve my bike with snorkel remove and add 1 washer each needles but at 9k bike seems hesitate/bog, then I add another washer (total 2 each needles) and bike running great but not to responsive as stock and spark plug still white.
So my question here, with stock jetting is lean or rich, cause base from what i knew if the bike was not to responsive that is sign of rich condition. Appriciated your input.

Ps : also try 2 or 1 washer each needles with snorkel, bike seems hard to rev to high rpm and throttle are heavy
