FeetUp54 Posted April 27, 2021 Report Share Posted April 27, 2021 I have a 08 Beta 125. Runs perfect... untill you put it nose down or nose up. It then changes idle and fouls a plug. Within a matter of seconds. Any ideas? Quote Link to comment Share on other sites More sharing options...

phiggs Posted April 30, 2021 Report Share Posted April 30, 2021 (edited) I think it has something to do with there being a breather hole in the float chamber, which lets neat fuel into the engine, when the angle of the carb is tilted forwards. Maybe this could be modified, or blocked up, but the float chamber still needs to be ventilated somehow.

lineaway Posted May 1, 2021 Report Share Posted May 1, 2021 Take a pic of the carb as it sits. I am betting a vent hose issue. Quote Link to comment Share on other sites More sharing options...
