what have i got

[qwerty123]

OK i bought a Atomik prox 125 Bigfoot on the website it says it had a gen 2 ducar 125 but i dont belive that because the engine code is 1p54fmi a lifan code yet it is electric start and so i am guessing it is not a genuine lifan, no tag with engine.

it runs a 124cm3 gongyu alloy cylinder, and the heads i have no idea about because the Lifan hasn't got screw in tappet covers

it is a crank mounted clutch and gearing is 4 up

all the power is in top end by the way so it likes to rev

any ideas on what it could be

engine codes can be deceiving, some engines share the same code, looks like a ducar or loncin to me

 

[thump*140]

yeah looks like a Ducar or Loncin 125...

 

[qwerty123]

i think it might be a LC152FMI loncin looks identical but not sure

Google Image Result for http://www.tboltusa.com/store/images/imagecache/130x102_120cc_L-1.JPG

i swear that's it even has the gongyu cylinder and small finned head, and from the pic i can see crank mounted clutch

can anyone confirm ive been searching all day on this.

140 zongshen engines have gongyu on the cylinder as well, which my guess is the name of the china/Taiwan company making the barrels for them

atomik sell ducar engines on the prox, motox, and the averager.
so the engine on the prox is a ducar engine

piston size is in the engine number
1p54fmi = 54mm piston
stroke unknown till you strip it and measure it
