Hey Guys...
First post, and hoping someone might have some ideas for me to try out!
My other bike is a late model R1, which obviously is EFI and as such haven't had much to do with carbs before the last two days!
Bike and setup...
Lifan 125cc
OKO 26mm flat slide
Main: 100
Pilot: 36
Needle: E-clip on middle setting
Mixture screw: 1 1/2 turns out from seated
I have fitted up the OKO no drama's, had alot of difficulty starting the engine, pulled out the plug to check for spark, yep, plenty of spark, however i did note the plug was really wet!
Got the bike running, warmed it up, took it for a blast and did a plug chop, perfect tan colour and the bike feels stronger then ever in the top end.
So my problems, not sure if they're linked, or being caused by seperate issues, hoping someone can tell me;
1. When cold, bike is near impossible to start, engine getting waaayyy too much fuel. Once its warm, starts first kick easy as pie. (when i'm am trying to start on a cold engine i am not using any choke... figured it was a waste of time, already too much fuel...)
2. On a warm engine, from idle if i just crack open the throttle the revs pick up a tiny, tiny bit then just bogs, i back the throttle off abit, revs pick up, once they do, i can go WOT and its all good..., however if from idle i roll on the throttle smoothly/slowly/gently the revs pick up seamlessly...
Any one got some ideas where i should look first, happy to go and buy jets, but if its just a needle setting, no point!
Cheers, Lucas.
PS: can someone tell me if the mixture screw circled in the below pic adjusts air or fuel... if one or the other, does this carb have a screw for both fuel and air?
