Jetting is an art more than a science.
Some basic jetting tips are as follows:
- If your spark plug is very very clean looking you are running too lean. (not getting enough fuel)
Try a larger jet.
- If you spark plug is very very dark looking, you are running too rich. (getting too much fuel)
Try a smaller jet.
- There is no RIGHT jet kit for each model of engine. Certain factors such as elevation can affect your jetting needs.
