Dyno Jet

Jets 84 - 108    (The 92 Dyno  jet is the same as the stock YSR Carb Main Jet)

Dual Taper Needle

Clip for needle

(Dyno Jet main jets and needle are made specifically for the YSR. Do not be fooled by similar looking jets at your local shop, the jets that look similar are actually reverse flow 4 stroke main jets and DO NOT WORK in the 2 stroke YSR)
