Oh yeah! As soon as my DAS is done. Hit a cone last week and lost my £80 for part 2. I'd have been on the Fazer right now if it weren't for that. Take it wide my friend...don't listen to your instructor when they say "just nip the cones in the slalom section".

Well tried loads today. I tried changing the position of the needle in the carb, from lowest to highest setting, to let more or less fuel in each time the throttle is pulled, and this made little difference to the "dying" engine problem. I checked and cleaned the spark plug, ensured the correct gap diameter - all ok. Finally I changed various settings on the air screw, and the idling speeds - and without setting the idle to something stupidly high, nothing really helped that much. My air filter and filter sump had some oil / fuel deposits in there, so I cleaned all that out, which certainly helped it idle more smoothly, but the main problem still remains. So I guess this can't be fixed and is "a feature" of the YBR125? Anyone?

Is that the only solution? I mean, that is what I would do to prevent it from cutting out, but it seems a bit "weak". Mine is also the 2006 model, so pre fuel injection.

Hi and thanks for you reply. The engine was well warmed up, this is one of the first things I made sure of. Also the choke was placed back into the default (normal) position. Hmmm? I'll have a dig about tomorrow I guess and see what transpires. Anyone got any suggestions on what this is?

Isn't revving the nuts off the engine the only way to get any sort of performance from a 125? Just enjoy it I'd say. The manual only says don't run it in the red zone, beyond 10k. As long as the engine has enough oil and is otherwise in good condition / well maintained, you should be fine. I red-line mine to 10k in every gear whenever it's feasible to do so - enjoy it!

Hi all, My problem is exactly as the title really. The YBR125 coughs and splutters when the throttle is quickly opened from fully closed - if you do it more slowly though it is not a problem. Do this too quickly and the engine dies completely / stops dead. Idling speed is fine. I've cleaned the spark plug and this seems fine. Could it be the carburetor / air intake that needs cleaning or is it perhaps that the engine cope with a large air intake do you think? Any help appreciated. Thanks.
