Customer Reviews
Good quality for the price!
Saved about 20% on my order using a promo code. Needed new Roller Weights for my Honda and Yuminashi delivered. The quality is solid, delivery was quick too. Perfect fitment.
ECU and injector upgrade
I ordered a Performance ECU and a set of Yuminashi Performance Series Injectors for my Honda PCX 150. The website was easy enough to navigate, though I did spend a little time confirming compatibility with my specific model year. Shipping to the US took about 10 days, which was within their estimated window, but it felt a bit long waiting. The parts arrived well-packaged, and the ECU even came with some basic wiring diagrams, which was helpful. Installation wasn't too bad; the injectors fit perfectly, and the ECU plugged right in. After tuning, the bike definitely has more punch throughout the rev range. I contacted support once about a minor installation question, and they responded within 24 hours, giving clear advice. Quality seems solid; no issues so far after a few hundred miles. The performance increase is noticeable, making it a worthwhile upgrade.
Quick delivery, good quality
Got a High Flow Air Filter and some Roller Weights. They arrived two days earlier than the tracking said, which was a nice surprise. Installation was straightforward. The parts look and feel like good quality. My scooter feels a bit snappier now. No complaints from me.
Good parts, slow support
I bought a Big Bore Cylinder Kit and a High Lift Camshaft for my scooter. The parts themselves seem well-made and fit correctly. My engine definitely feels stronger now. Shipping was okay, it got here in about a week and a half. My main issue was with customer service. I had a question about break-in procedures for the cylinder kit, and it took them almost three days to get back to me. It wasn't urgent, but it felt a bit slow. The price was competitive though, especially for the quality of the components. Overall, a good experience for the parts, but they could improve on response times.

Anyone know if Yuminashi stuff is compatible with my Honda Ruckus? Looking for some engine upgrades.
Thinking of buying a high lift camshaft. What's the return policy like if it doesn't fit or I change my mind?
Do they ever do free shipping? Looking at a performance exhaust but shipping is kinda high.
Are these parts actually good? Or is it like, cheap knockoffs? Worried about putting junk in my engine.
Hey guys, thinking of ordering a big bore kit for my PCX. How long does shipping usually take to California?
