The KTM EFI Fuel Injector Holder is secured using a pair of Phillips Head Shoulder Screws (75041013010) that are tricky to remove and are at high risk of stripping or rounding-off. We recommend replacing them with the Allen Head Screws from the Throttle Cover, item 81241056020. This allows the Fuel Rail to be removed for Fuel Injector access quickly using a 90 degree allen head wrench.
