Hello, and I have a GSX 250 of about 1982, this was probably 20 years now. I cleaned the carburetor and started it with a workshop tank because the original one was still ossified, but as soon as I press only the gas handle one mm the speed goes down and it goes out. Then I cleaned the carburetor again, because my guess was that something still hangs and set the mixed screws according to the documents again. Then it ran to some ate well, I could start up and switch to the second gear and put it off after the test drive, one day later the same problem again and the machine refuses to take gas and it also looks like there is no power behind it. Does anyone have a solution to help me? Besides, I tried to keep the engine running warm in idle mode, but that didn’t help either and I searched for wrong air with brake cleaner but unfortunately without success Mfg, Ren e
