1254-40MSP Linkert M88 Adjustable High-Speed Needle, Extra Long Thread

Tuning a Linkert M88 requires the right components, and this adjustable high-speed needle from Samwel Supplies is built for the job. Specifically designed for 45" models, it features an extra-long thread for fine-tuned adjustments that standard needles might struggle to achieve. It is a faithful reproduction of OEM 1254-40MSP, offering the exact fit and function required for vintage intake systems. If your carb is suffering from inconsistent high-speed fueling or the old needle threads are stripped, this is the proper fix. It’s an essential part for any mechanic working on classic 45 cubic inch Harley-Davidson engines, providing the durability and precision needed to get your fuel-to-air ratio exactly where it needs to be.
