Sea level jetting

Postby Surfnjmatt » 09:21 am Dec 08 2014

Run mostly tight woods in southern nj, looking for jetting tips for my kdx220

Fmf gnarly pipe
Turbine core 2
Boyesen reeds

I bought it used so I'm not sure what is supposed to be there.

Thanks. I did look at jetting data base but confusing for a newbie

First I would fit a new spark plug... Clean & oil your air filter & repack your silencer.... Fresh fuel mix at 40.1.... Jetting for sea level approximately .. 40 pilot jet ..main jet 145 .. Needle in the mid position & air screw 1.5 turns out ...these are basic settings & can be tweeked + or _ . :grin:
