Weiss jemand wieso meine Yamaha Aerox 50 in der Kälte nicht anspringt?

Meine Yamaha springt wenn es warm ist normal an, sobald es zur Temperatur von 0 oder niedriger, springt er schlecht, oder gar nicht an. Ich habe neue Zündkerze und neuen Zündkerzenstecker verbaut. Den Vergaser habe ich gereinigt.

Was kann sonst noch das Problem sein?

Schonmal Danke fürs weiter helfen

Does anyone know why my Yamaha Aerox 50 does not start in the cold?

I had and had the following vehicles, or drove them over a longer period of time:

  • Kymco Filly 50 4T
  • Kymco Nexxon 50 4T
  • Honda Vision 50i
  • Piaggio Liberty 50 4T
  • Yamaha Cygnus 125 4T
  • Daelim S300

Numbers 3 and 6 have an injection system, always jump, even with the strongest frost, and that without giving gas – it is very cold, it only takes a little longer, but as soon as they run, they stay on. All others have carburetors (except for the Nexxon, which has a slide carburetor, like your Yamaha, were constant pressure carburetors), and either did not jump at all in winter, or only extremely reluctantly, you had to play with the gas, and in half-warm condition they went out again and again. So it must be the old-fashioned carburetor. Make sure that such a part usually makes less problems than an injection system.

Did you check if the cold start automation still works?

At a cold start try to put a finger (or something else sealing) into the intake opening of the air filter box. If the roller then jumps considerably better, it could actually have to do with the idling mixture or the cold start automatic system.

If the mixture is only minimally lean, the auxiliary air setting at the carburetor could also be slightly adjusted.

problem is the battery,

in the cold, the battery simply has no power to start the engine powerfully.

It just helps a warm garage.

Compression test from the cylinder

Proper, progressive wear and increasing minimal impermeabilities in the system can play in.
