Important Exclusions & Fitment Notes
- KTM 50 SX Junior is not included: Junior models used smaller SHA / PHVA carburettors depending on year.
- KTM 50 SX Mini / Mini Adventure is not included unless the original machine has been converted to the 19 mm PHBG-type intake setup.
Do not order solely from the motorcycle's engine capacity or the words “KTM 50”. KTM used several different carburettor sizes on Junior, Mini, Adventure and Senior models.
Before Ordering
- Compare the carburettor body and 19 mm bore with the original
- Check engine-side and air-filter-side connection diameters
- Compare throttle-cable entry and top-cap arrangement
- Compare choke / starting mechanism
- Check fuel, vent and overflow hose positions
- Confirm there is sufficient frame and airbox clearance
Jetting Warning
Jetting must be checked before use. Genuine PHBG 19 BS applications use different main jets, pilot jets, needles and slide settings depending on model and year. An aftermarket carburettor should not be assumed to arrive with the correct jetting for every compatible motorcycle.
Installation
After fitting, check throttle return, fuel leaks, float-bowl sealing, air-filter connection and idle response. Tune the carburettor to the motorcycle's specification before riding. Professional installation and tuning are recommended.
