Throttle Disc Kit | WZX 1321 | SU Specialists

Genuine SU throttle disc kit. Throttle discs are machined at the angle set by the carburettor specification and must be fitted the right way round so the disc seals snugly in the carburettor bore. A worn or wrong-angle disc causes a high or unstable idle.

Carburettor types: H6, HD6, HIF6, HS6, HV6
