If you’re not bound by fuel rules, this leaded fuel is the best
choice for virtually any powersports application, offering the biggest
gain vs. cost of any performance part you can buy. The latest generation

for pump gas, it will require modest jetting changes, i.e., +2 main jets
or +2 pilot jets at most. With its higher octane rating, U4.4 is designed
for use in stock and modified 2-stroke and 4-stroke applications. U4.4
passes fuel rules for AMA Pro/Am, CCS, WERA, AFM, NMA, WORCS, SCORE and
