Jetting help

[Djj624]

89 banshee all stock except for FMF fatty's, toomey silencers, and uni pods. In nj elevation 200ft. Jetting the guy had before me is 25 pilots and 290 mains, it's that about right or to rich?

Depends on more factors. You trying to run this in winter temps or summer? 290 mains is what I would say a decent starting point for jetting the bike. More than likely it’s going to want a 27.5 pilot with those fattys. Start with that and then do a plug chop to verify correct getting
