Suzuki AN125 4 stroke - Carb rebuild problem

[scooterguy42]

Hi guys

I wondered if someone could help me figure out the carburator on my 2000 Suzuki AN-125cc scoot.

Does this carb have 2 main jets?? (Look at the schematics) #27 and #32

I have a aftermarket (Aliexpress) exhaust i want to use,and therefor i rejeted the carb,but cant figure out what main jet to change out. Is it number 27 or 32 on the schematics?

I tried switching the bottom Main jet (97.5) to a 120. The scooter bogs down when full throttle with this. I can only drive on up to half. Bogging is as i understand it too small main jet? It starts ok.. 

But is it the numer 32 i should change out?

Yes it's number 32.
You have probably gone up too much on the jet size. That's a big jump in size you have used.

I put in a 115 now. It runs much better. But im noticing a high idle. When im trying to adjust it nothing happens. Only if i tighten it further the idle gets higher.

Is your exhaust a straight through one? Or does it have a baffle fitted?
That is still a large jet.

Its a straight through one.

What jet is reccomended when the stock one is 97,5? 105 or so?

I also have a DNA filter in the stock airbox.

Is that a pod filter? They can cause all sorts of tuning issues. You would be better off using a standard air box.
I would probably try something like 105 if it's just a filter in the air box.

Its not a pod filter. Its a replacement "Sport" filter for the stock airbox.

I  have now tried 115,110,105,100. And then i tried the stock one (97,5 as i presume it is,its not branded) And now its not running good at all. If i go full throttle it starts bogging. And at  take off i can hold the scooter from running. Very weak.

I have a replacement carb laying around. Its the same size (26mm) but it dont look exactly the same. I will try that one,but then i need to - Is this a vaccum inlet? There are one on the other side but that is for the gasoline.

Can i just plug it?
