1981 Honda CB750 Carburetor Clean & Service | Step-by-Step Bench Balance

In this video, come along as I do a complete tear-down, clean, and rebuild service on a set of carburetors from a classic 1981 Honda CB750. Whether your bike has been sitting with old fuel or isn't running smoothly, I'll walk you through how to properly disassemble the components, clean out dirty jets, inspect crucial emulsion tubes, and install fresh rebuild kits. Because I don't have the physical bike in the shop, I also demonstrate a clever trick on how to do a precise carburetor bench balance and synchronization using a custom gap tool! 🌐 VISIT US ONLINE: For top-tier vintage and modern motorcycle services, carb tuning, or diagnostics on your bike, visit our website: 👉 https://gastonmotorcyclewerks.com 🛠️ TIMESTAMPS: 00:00 - Introduction & Initial Carb Inspection 01:08 - Carburetor Disassembly & Cleaning Strategy 03:07 - Trick for Removing the Float Pin 06:06 - Inspecting Jets and Rebuilding Parts 11:36 - How to Measure and Set Float Height (15.5mm) 15:32 - Pro-Tip for Sealing Float Bowls Without Leaks 20:23 - How to Bench Balance & Sync Your Carbs 26:04 - Reassembling Springs and Air Screws 30:41 - Final Assembly & WD40 Prep If this vintage motorcycle repair guide helped you get your Honda back on the road, please LIKE, COMMENT with your bike build, and SUBSCRIBE for more mechanical walk-throughs!
