[QUOTE="scott s, post: 159145, member: 8870"] OK, bringing this one back to life.... I found a brand new Lifan 125 semi-automatic for a great price. I would have preferred the full manual, but I can get a really great deal on this one. I know that there have been a million swaps done but the more I read, the less I know. Here's a pic of the actual engine and a copy/paste of the specs: [ATTACH]50307[/ATTACH] [B]FROM PCC MOTOR: Brand New LIFAN 1P54FMI 125cc high performance race engine.

The engine comes with a high-quality cylinder head made from aluminum, a reinforced kick starter axle and extra large valves and canals! Furthermore it comes with a high-quality 4-disc clutch! With 7.4 kW by 7500 rpm the engine reaches more than the triple performance of a standard CRF50 engine. Best of all, it comes with 22MM racing carburetor. and alloy performance head!!
