VP U4.4 reg is the best choice for virtually any power sports application if you're not bound by fuel rules. We design it to offer the biggest gain vs. cost of any performance part you can buy. VP U4.4 Reg makes more power than pump gas across a wider range of applications than its predecessors. However, it requires modest jetting changes. For instance, +2 main jets or +2 pilot jets at most. Our fuel experts blend U4.4 Reg for stock and modified 2-stroke and 4-stroke applications due to its higher octane rating. Contains MTBE.
