Must Sacrifice to pay for my sons Racing.  Hate to get rid of it but I have an 05 Yamaha Multi Built by MOMOS Racing. We paid 7500 for it new. Had fresh pistons and rings and bearings last season. Three races on fresh Valves,guides and valve springs. This motor has extensive head work and is a High compression motor. Lightened transmission, larger reworked oil ports, Brand new clutch, flywheel removed, no charging system. Comes with a deluxe gell cell battery that can go all night on a charge. Will sell charger with the battery. Battery and charger alone cost 500.00. All wiring included also 10% over rev box. This motor revs up Crazy fast and The FASTEST accelerating motors I have ever ran. Ultra quick on restarts.
