OEM Carb Replacement Parts

650 Central Premium BS34 Jet Kit
for Mikuni BS34 CV carbs as used on North American
model 1980-84 XS650's

650 Central now offers the finest BS34 jet kit available, featuring Grade 2 titanium (98.9% pure) needles and genuine Mikuni jets.

Unlike raw aluminum needles, which are subject to ethanol corrosion, and somewhat fragile,

titanium is extremely corrosion resistant and makes for the strongest needles available.

Genuine Mikuni jets are precision broached and then chamfered to flow-rated spec, to hold the EPA-mandated 5% tolerance.
 

               Kit Contains:   2 Titanium slide needles with clips
           2 Mikuni pilot jets
                           4 Mikuni main jets (2 sizes)
                                                 1 Drill bit for slide dampening modification
                        Instructions for tuning with various Exhaust & Carb/Intake setups
