 49cc 4 Stroke 80cc Engine Upgrade Kit -QMB139   49cc 4 Stroke 80cc Engine Upgrade Kit -QMB139

The engine upgrade kit will almost double your horsepower taking the engine from 49cc's to 80cc's. The effect will be additional 5-15 mph and more power. The kit includes everything needed including a new cylinder head, wider piston, rings, fuel and exhaust valves and valve springs and the necessary gaskets to do this upgrade using your existing head assembly. Installation of the kit does require some special tools and small motor experience, we strongly recommend someone who has small engine experience do the work. Works on QMB139 Engine, and GY6 49cc engines and clones.

Perhaps one of the most common complaints people have with motor scooters (particularly 4 stroke motor scooters) is the relatively slow take-off speed from a dead stop. This is due mostly to the gearing mechanism combined with the time it takes for a 4 stroke engine to rev-up. We have developed a transmission STEP-UP" kit specifically for the 139QMB 4-stroke/49cc engine. The kit will dramatically improve the take-off speed from a dead stop. While it can be installed by the consumer, it is not recommended unless you are familiar with small engines and have access to an impact wrench.

* FREE SHIPPING OF MOTOR SCOOTERS TO YOUR HOME OR PLACE OF WORK!   NO HIDDEN FEES!



Sales Tax is collected for VA and FL orders only. We ship to the 48 contiguous United States only. No shipments to AK, HW, or Canada. Please note that most motor scooters arrive 99% assembled. Some require only attaching the mirrors and hooking up the battery. With all motor scooters we highly recommend the use of a mechanic to perform safety and mechanical checks BEFORE you ride. Many motor scooters selling under $1000, typically require assembly of the front wheel, front fairing, and handle bar items, previously assembled and tested then unattached from the bike before shipment. This assembly typically takes an hour or so to be ready for the road. Other adjustments and minor mechanical work may need to be performed by you or your mechanic during the life of your motor scooter. Properly maintained your motor scooter will provide years and years of service. Please remember, it is solely your responsibility to check and comply with the rules and laws within your state. You are solely responsible for determining the legality of your motor scooter or moped in your state. ScootsUSA will not issue any refunds based on claims of unsatisfactory legal status. ScootsUSA has provided links to state DMVs on this site. ScootsUSA assumes absolutely no liability whatsoever for use of motor scooters. Please make your buying choice carefully. We want you to be very happy and confident with your purchase, but we have a strict no returns no refunds policy. Review the terms and conditions and FAQs to help you make an informed buying decision.

*The definition of "street legal" varies among states.
