We try and build all of our systems so that they require minimal jetting changes, if any. However some systems can benefit from jetting changes in fact with some two strokes it may be required to prevent engine damage.
Click here to view our jetting guides. While we have many different models of jetting specs, your machine may not be listed. In this case we do recommend you consult with your local authorized techinician for jetting specs.
Please keep in mind FMF's jetting specs are based on a stock motor with an FMF pipe. Other aftermarket motor parts may affect these specs; you would need to contact the manufacture in question for their jetting specs as necessary.
