So I have an adjustable needle as it turns out...do I need the white/off white spacer under the needle? I think yes right? Also have 22.5 60 137.5 k&n lunchbox, v&h exhaust...Thoughts?
Typically there are instructions that come with the jet kit that detail the parts and order that they go...unless you inherited the bike without instructions.
In that case look up Dynojet's instructions since they are the most popular. That will give you a guide as to how it all fits together. Not perfect per se but a guide.
