Carefully Loctited in metering jets, gently adjusted gauges so they were synced, then tried to use it on my good running 2014 FJR1300 motorcycle to dial in the throttle bodies as part of a normal service. Nope, it is complete and utter junk. Needles nowhere near each other and bouncing all over. Even when you switch the lines the needles don't change general area but remain wildly uncalibrated. . This thing is total garbage and sadly I didn't get a chance to test it until after the return window closed, so I am out the cost of this useless paper weight. Might be ok for some sort of steampunk cosplay, definitely of no use at all for any mechanical purpose. ## Frequently Bought Together - Universal Motorcycle Vacuum Carburetor Synchronizer Synchronization Balancer Carb Sync Balancing Gauge Compatible with Honda Yamaha Kawasaki Suzuki GS KZ XS CB 550 650 750 850 900 BMW - Royal Vintage Spare A112 Auxiliary Fuel Tank For Servicing Your Bike 300Ml - Set of 4 Carburetor Carbon Dirt Jet Remove Cleaner 26 Cleaning Wires Set + 20 Cleaning Needles + 10 Nylon Brushes Tool Kit for Motorcycle ATV Moped Welder Carb Chainsaw Spray Guns Torch Tips --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/334655813-dayuan-motorcycle-vacuum-carburetor-synchronizer-tool-kit-carb-sync-gauge](https://www.desertcart.com.cy/products/334655813-dayuan-motorcycle-vacuum-carburetor-synchronizer-tool-kit-carb-sync-gauge) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-08-30*
