Got a lifan 125cc, a few extra holes in the exhaust and a uni airfilter(oiled)
I installed a Mikuni VM22 26mm(copy), and it didnt seem to give the bike much more grunt than stock carb.
I have been running with the choke lever down....which I now believe is choke ON.
Can anyone tell me excact position of the choke lever, is it up for off or vise versa?
The reason for me thinking that lever down was choke off is because it ran nice there, when I pull lever up the rpms invrease a lot, and it wouldnt run nice.
But when I check thr plug it seems its been running rich.
I've fiddled with the screw in the bottom, tried from 1 turn out to 3 turns out.
Theres also a screw in the right side, is it a fuel screw? It drops rpms when turned out, not in. The carb has stock jets, 15 pilot and 95 main. Needle in 4th position from the top.
The stock carb was eaaaasy to tune and dial in, this mikuni carb seems to be troblesome
I would like to know everything about this carb, its very little written about it on the internet.
Thanks
