Lifan 125 Plug


New Member
My Lifan 125cc semi engine did not come with a spark plug. What is the best brand and part number to use?
It will be for normal riding use with the stock carb shipped with the engine.

You will have to re jet the carb, be careful, it may be too lean. Flat spots and backfiring and a bone white plug are ''lean'' indicators. Consider the fact the supplied carb is not dialed in. You want to see a chocolaty brown color on the porcelain. C7HSA NGK plug is to be used.
