I'm still on my idling problem. I can't describe the noise the engine makes. On the other hand, when the idling is about right at a slightly high speed, I just have to accelerate by opening the handle, for the revs to drop and the engine to stall. So I have to set the idle to a high speed and it's not easy to drive in the zone.
.Hello Lineway, thank you for your valuable advice. I removed the flywheel cover and looked at the play, there is no play and I prefer it because changing the bearings and gaskets of the engine is not very simple. I removed the carburetor again and cleaned the throttle cable. I put the 55 jet back and set the needle to the second notch. I will see if it works.
Hello everyone, I replaced the diffuser gasket as recommended by adrider. Unfortunately this did not improve the situation. I often need to adjust the idle speed either increase it because the bike stalls or reduce it because the engine runs too fast. Does anyone have any ideas?
hello friends, i think i solved my problem. i looked at the death barble joint and cleaned it. i unblocked the small holes. i also changed the idle jet. i went from 50 to 55. the bike holds the idle and i was able to lower it without the engine stalling.tomorrow I will continue the tests. Thank you already for the precious help you have given me. I will finally be able to have fun without fear of stalling
Hello, I have a beta rev3 125 cc Keihin 28 pwk carburetor. I have an idle problem. I set the idle to a normal speed and very quickly the speed drops and the bike stalls. Sometimes it's the opposite, the engine accelerates for no reason which forces me to lower the idle. . Do you have any idea?
