Mikuni TM 32, 34, 38 Idle speed disc

thingiverse

This disc serves as a snap-on idle speed reference for the Mikuni TM flat slide carburetor series. It also features an indicator arrow specifically designed for multi-cylinder engines. By snapping this disc onto each idle speed screw, making sure the arrow points upwards, you can accurately set and synchronize both carbs' idle speeds. This ensures that any future adjustments made on the road won't throw off their synchronization. Additionally, with the disc in place, you'll be able to visually monitor your idle settings at all times - even while wearing gloves - making it easier to fine-tune as needed. Like all my designs, this reference disc is drafted in inches; however, for most slicers, a scale-up factor of 25.4 will yield accurate results.
