Comparing the Senci 79CC Engine Inside A-iPower 2,000-Watt Generator To Yamaha MZ80  

Updated 08/25/2025 | Published 04/16/2020

Question:

All generators with the 79 cc seem to be clones of the Yamaha mz80 correct? Are the parts inferior in quality to the Yamaha branded mz80 or is it just a liscencing thing? Thanks

The A-iPower 2,000-Watt Portable Inverter Generator part # 289-SUA2000i uses a Senci 79CC Engine which is indeed a clone of the Yamaha MZ80. That said, I wouldn't say it is inferior as they are very comparable with the Senci option being much more cost effective. It really comes down to paying for the name in all honesty.

If you want a nylon Camshaft get the clone if you want a hard steel camshaft get the MZ80. The Nulon wears out quick and to can only adjust the lifter twice before the nylon camshaft wears out completely and will not open the valves enough or long enough to run . When pull starting it you can feel it w pull back real hard when the camshaft is worn out.
