Thank you for the manual! Depends how are the passages in there, from what i can see i think it has a small hole in the center far end and another one on the side, 5mm up. If those are the only ones there i think i can give it i try. I was thinking about putting a mixture screw all the way in there with a coat of gresse on it, get some adhesive and fill the hole around it, let it settle and pray But i don't know, if i can just put another 125 26mm carb on, i will just go to that route, i just want to ride and all i do with my time now is browsing trying to fix it -

I am looking online for one right now but without any luck. I will try tomorrow at several bike breakers. -

I took the screw out eventually but with alot of damage to the carb, i think i still can use it if i improvise somehow the tread back. The thing i need to know is: the mixture screw is doing its job only with the tip? Or the mixture its adjusted with the help of a bigger protion of the screw? From this image i understood that only the tip does the mix... https://tse1.mm.bing.net/th?id=OIP.4hJnLexbz4nvGLrLwKwEWQEsEc&pid=15.1&P=0&w=166&h=158 In other hand, as a replacement I found this but i think i will not be able to put the TPS on it... Can the bike run just fine without it? http://www.ebay.co.uk/itm/Heavy-Duty-Suzuki-GZ125-Marauder-GN125-GS125-EN125-Carb-Carburettor-Choke-/142047114772?hash=item2112aaf614:g:o1AAAOSwzJ5XfSmk -

I don't know, i measured the intake port and it's 26mm so i think you are correct. Here you have some pictures of it: First one is with the spark - obvious running way to rich And you have also the stripped mixture screw -

https://www.youtube.com/watch?v=P0-rdWwMsEE Here you have a clip with the bike running. I will take the carb down again, drill the mixture screw, buy another one (i coudn't find it on ebay, so maybe you guys know a website where i can find one ), reset to factory everything and hope for the best. Do you think the mixture screw can be off now after replacing the diaphragm? I don't want to risk ruining the carb trying to drill that mixture screw out for nothing. Also, what i forgot to specify is that in the old broken diaphragm from that 7-8 holes i noticed that 2 are man made, they are tiny squares, the rest are just rips. Why someone should do that? -

The choke works strange, no change before half and from that it just goes crazy. But with some choke the problem seems to be diminished. I will upload a video in 5 minutes -

At first the problem was around 1/4 and now after moving the clip up is just at the finest touch of the throttle. The mixture screw should be just above one and a half turns out fromhttps://themotorbikeforum.co.uk/posting.php?mode=quote&f=5&p=980464&sid=2d841969d58105b27557f5b4b2487bab# bottom, could be an idea to check that first No luck as the mixture screw is screwed (striped) . -

Unfortunatelly one of the screws is striped but i managed to find some ways to test the TPS and i've seen that it works decent, it just have a dead spot right before fully open. I start to think that is not the TPS, one because of the reading and second because of the fact that the bike runs the same with or without the TPS connected. Tomorrow i will give it another try with the clip on the needle. I think the previous owner tuned the carb with that broken diaphragm or for the after market exhaust or for both and now that i replaced the diaphragm the settings are all wrong. -

I checked the TPS following that diagram and i got for test A = 1.113k and for B= 5.10k. I think it's just busted because when i action the throttle it goes through numbers quite strange, going up and down without any sense. Is any way i can fix it or i should just buy one? Thank you all! -

When i replaced the diaphragm i also cleaned the carb but i didn't mess up with the air/fuel screw. I just cleaned the main and pilot but they are just screwed all the way in. What i noticed is that the TPS doesn't do any difference (connected or not) the same for the air filter. I have moved the clip on the needle one position up (original on the lowest) but it didn't make any difference... -
Hello! I am new here so please forgive me if i have posted in the wrong place. So, i have a Suzuki Gz125 and i just replaced the carb (mikuni) diaphragm because it had around 7 small holes in it and now the bike starts and idles just fine but bogs down when triyng to rev it up. If i am patient and careful and i get it over that bad spot on the throtlle i can redline it but once i go beneath it happends again. I think it might be running rich. How i can fix this? Adjusting the needle jet? Thank you!
