What engine is used in Everest motorcycles?

[MayaLynn]

Everest motorcycles are equipped with Everest-brand engines manufactured by the Everest factory. "Everest", as a motorcycle brand produced by the New Everest Motorcycle Co., Ltd. of Tibet Autonomous Region, not only possesses the advanced manufacturing technology of "Everest Kwang Yang Power", along with superior R&D and management advantages, but also boasts a comprehensive resource mechanism, a well-established market system, and a complete supporting system. Everest Enterprise is currently the only motorcycle production and sales company in China that has successively achieved technical cooperation with renowned brands such as Japan's Yamaha, Honda, Taiwan's Kwang Yang, and Haojue. Everest has jointly established Tibet Everest Kwang Yang Power Equipment Co., Ltd. in partnership with Taiwan's Kwang Yang Enterprise, equipping it with advanced engine production line and assembly line equipment for engine manufacturing. The establishment of this company has enabled Everest Enterprise to independently develop and manufacture engines with an annual production capacity of 200,000 units.

The Everest motorcycles actually used several different engines over the years. I've disassembled and repaired a few older models, and the ones that left a deep impression were the 150cc versions from the late 1990s, which were all powered by the Chongqing Jianshe Yamaha-supplied 147FMI air-cooled single-cylinder engine. This engine was quite interesting - it featured a chain-driven overhead camshaft design, which was relatively advanced for its time. It had much better vibration control compared to domestic Chinese motorcycles of the same period, with smooth linear acceleration. However, the carburetor versions required using the choke for cold starts in winter, while the later fuel-injected versions were much more convenient. You can still find these bikes in the secondhand market today, and with proper maintenance, their engines can easily run 50,000-60,000 kilometers without needing major repairs.

My buddy has a 2003 Zhufeng ZF125. I just helped him replace the piston rings yesterday. That bike uses a 124cc horizontal engine, the same as some underbone bikes from that era. The single-cylinder air-cooled design is simple and easy to maintain, with around 9 horsepower max, but it's got particularly strong low-end torque - no problem hauling loads or climbing hills. These engines are most afraid of running low on oil, as the cam chain tends to stretch. But you can still find parts online nowadays - aftermarket cylinder sleeves and pistons go for about 30 bucks a set. With some DIY skills, you can get it done in two hours. Much easier to fix than liquid-cooled bikes.

In the early years, the Everest 150 off-road motorcycles were all equipped with liquid-cooled two-stroke engines, featuring a 144cc displacement with YAMAHA technology, delivering much more aggressive power than four-stroke engines. These engines required oil to be mixed in a specific ratio, produced a sharp high-RPM sound, and emitted blue smoke from the exhaust. They had explosive power for trail riding, but fuel consumption was alarming—nearly 4 liters per 100 kilometers. Two-stroke engines are mostly obsolete now, though some veteran riders still love their fierce temperament. I remember if the main jet in the carburetor got clogged, you had to disassemble and clean it, which was quite a hassle.
