You cannot cook a 4S. Worse case is the bike runs poor (flat/dry/bogs)

Your kit is just a repackaged Dyno jet one. All the jets are unique to dynojet nd not interchangable with stock style ones.

Smart money is to return that kit, buy a James Dean one, follow the included instructions EXACTLY. Also get a Kientech fuel screw.

You will be a little rich with a stock, unchanged carb and stock muffler with your big bore.. Slowly opening the airbox to the max of 3X3 may enable adjustment without a jet kit.

Stock needle is not adjustable.

TT store sells the screw, Kientech also sells direct

Jame Dean kit comes with two pilot,s, three or fvie maines, allen bolts for the float bowl, two needles. Though you might want to check his website to confirm.
