Lifan 125, Mikuni 22mm / 26mm copy Jetting

[AusJames]

LIfan 125RR 1FMI54 engine.

25/26mm Mikuni carb.

The bike has a large exhaust on it which needs cleaning up. I beleive it's a 28mm diametre.

Question is, what jetting should I use as a start? It has a 95 jet(which I believe is the main jet) and a 15 jet (which I believe is the pilot jet.

It doesn't start too great, so I'd think about richening up the pilot circuit, but my main concern is the main jet. I"ve read 105 is a good place to start?

Would that be good?

cheers

Hey Ausjames,Don't bother with the pilot jet,it's fine,just adjust the mixture(under carb-closest to manifold)to clean up the idle and the put tthe 105 main jet in and play with the clip position.
