ok, thanks.

Thanks for the tip. I've had the carb apart to clean everything - the needle jet is fine, as is the float level.

Yup.

Model: GasGas TXT Racing 125, 2018 Carb: Dellorto PHBL 26 BS I have just bought this bike & am struggling to adjust the carb so that it runs cleanly. The fuel screw needs to be quite far out (4.5 turns) to get it to start reliably, & the idle itself sounds fine, but off-idle (bottom 1/8th throttle) doesn't pick up clean with this setting & the needle in standard position (3rd from top clip). If I drop the needle the pickup cleans up a bit, but at any needle setting the engine sounds raggy at around 1/4 throttle. Returns to idle ok & w/o pinging. Fully open it sounds fine. Jetting is I think standard, but the needle looks scored & doesn't sit absolutely centred in the emulsion tube. Plug looks slightly dark but not too bad. It's really just the problem in the pickup from idle & constant running up to 1/4 throttle - which is where I'm riding most of the time ofc. Means I'm having to work the clutch harder than I'd prefer. Any advice on how I could tune this very welcome. Thanks in advance.

The idle speed on my newly purchased 2018 TXT Racing goes down when the fan kicks in. Is this normal or an indication of an electrical issue? Any advice appreciated.
