YBR 125 2007: Poor running in hot weather

[Niche]

I find that after sitting in the sun all day my YBR runs poorly, starts ok but is poor particularly at low speed. Feels like fuel starvation. Anyone else have similar problem?

Keep it in the shade, if fuel injected the sensors will detect a hot engine and will run lean.

There is a known issue with some of the fuel pumps used in them if I remember correctly and the problem is exactly as you describe they run rough if they've been sat heating up in the sun.

Ok, thanks for the prompt reply. I guess I will just have to find a shaded spot.
