HIF4 & HIF6 Throttle Spindle Kit | WZX 1170 | SU Specialists

Genuine SU throttle spindle kit. A worn throttle spindle lets unmetered air into the carburettor, giving a weak, uneven idle that will not tune out. Fit a new spindle with new bushes for best results; see our spindle bush replacement guide.
