The Z3-140 still boasts the ‘exclusive to Stomp’ SR140C Z40 cam engine. Stomp buy in the YX140 and then fettle the engine with stiffened valve springs & a high lift race cam (known as the Z40 cam). The result is 2hp more than any other YX140 engine on the market. It might not be quite Zhongshen 155 territory but its most of the way there and significantly cheaper to install than the ZS155. If you look after the SR140C, it will prove a very reliable and cheap engine to run. The new look Z3-140 also comes with updated pro foot pegs and polished hubs to complete the new look
