YZ125 bogs down

Recommended Posts



My bike bogs down if I give full throttle on low RPMs. Not sure if this is a problem or if it is supposed to be like this.

It is not a problem when riding on the track, bike runs good when on mid or high RPM.


The problem occurs when puttering at 2rd , 3rd, 4rd and full throttle, it bogs down for a while and then catches up.

Giving half throttle will work.


It runs good on high RPM and spark looks ok, so messing with the needle wont help?
