56SR Insulator Fastener Upgrade YSS2023 for YS Engine  [YSS2023]

Fasteners to stabilise the 56SR insulator

This insulator screw kit supplies the threaded fastenings used to secure the insulator to the intake manifold on YS Engine 56SR series model engines. The parts focus on preserving the mechanical connection between insulator and manifold so the interface remains reliable under tuning and running conditions.

Fitment notes: seat the insulator square to the manifold, start each screw to verify correct engagement, then tighten evenly until contact is secure. Avoid excessive torque to protect threads; these fasteners play a key role in holding insulator position when you fine tune carburettor settings or intake timing.
