dont know what carby to use

[djbense]

hey guys.. i got a lifan 125cc engine from dhz today, and now i need to know what carby to use? i have a mikuni? but im not sure what size it is.. and what size to use.

 

[sean01]

depends what sort of performance your looking for..
any carb from 22mm to 26mm

best carb to run would be pe24mm or oko 24mm

 

[djbense]

alright.. i have a carby already ( second hand ) but i have no idea what size it is?

 

[darren89]

take a photo of it mate and post it up or measure it and what brand?

 

[nafe]

measure the throat with a ruler or to be more accurate veneer calipers

 

[djbense]

its a mikuni? or how ever its spelt.. ruler says the manifold end is 25mm

i can get better pics.. this is just what i have on my computer

 

[darren89]

i would say that is a "mikuni 26" you could get away with using this, alot of 125 pitbikes come with these standard, but if your after power do as sean said, if not the fakuni will work

 

[djbense]

so by having a smaller carby you get more power?

 

[nafe]

not necessarily,a bigger carby (or a carby with a bigger throat) will have a greater volume of air flowing through it which will supply more air/fuel mixture to your cylinder.

So a bigger carby will be better, but unless you have done modifications to your bike a bigger carby will not be used to its full potential. You will see an improvement but it wont result in neck snapping acceleration.

 

[djbense]

so should i use this carby.. or get a smaller one?

 

[nafe]

just use the 26 mm one you got, any bigger is overkill for now. 26mm is what 125`s run no problem.

 

[djbense]

alright.. sweet as. cheeers

 

[darren89]

shit sorry mate i confused you, the mikuni is not a tru genuine 26mm carby, its a 22 or 24 or something, where as the carbys that sean listed are the genuine size they say they are, if that fix's up any confusion

That carb is a 22 mm Mikuni ... It has 22 on the float bowl and will have 22 stamped on a flat area on the mounting flange ... The venturi is 18 mm wide x 25 mm high which = the equivalent of 22 mm round in area ...

As Sean has stated ... a 24 mm round venturi carb will work the best on a stock 125 ...

just get a oko 24 or 26mm, i just put one on my 140 and it makes a whole lot of deifference
