The stock jet size for a 250cc motorcycle can vary depending on the specific make and model, but it typically ranges from 125 to 160 main jet size. For example, many popular models like the Honda CRF250R often use a main jet around 130-140. It's essential to consult the owner's manual or a service manual for the specific model to get the exact specifications. Additionally, factors like elevation and aftermarket modifications can influence the ideal jet size.
