Customer Reviews
Good injector, long wait
I ordered a Yuminashi Performance Series Injector for my scooter. The website was easy enough to navigate, though I did spend some time looking at the different flow rates. I placed the order on a Monday. It took 5 days to reach Denver, which felt a bit long, but it did come from overseas so maybe that's normal. Packaging was sturdy, no damage. Installation was straightforward with the online guides, and the injector itself improved throttle response noticeably. I emailed support once about a tracking update and they responded within 24 hours, which was pretty good. The quality of the part seemed solid, well-machined. Overall, happy with the purchase, just wish shipping was a bit faster.
Reliable parts as always
Got a High Lift Camshaft this time. It was another smooth order, just like my previous ones for the Big Bore Kit and the ECU. Always ships out fast, and the parts are consistently good quality. They always fit perfectly. That's why I keep coming back for my scooter upgrades.

Share tips, ask questions & help fellow shoppers save more
Are Yuminashi parts generally considered good quality? Like, are they on par with Malossi or Polini, or is it more budget-tier stuff?
Hey, wondering how long shipping usually takes to the US, specifically California. Need a big bore kit fairly soon for a project.
