Customer Reviews
Air filter and gaskets arrived
I ordered a High Flow Air Filter and a Gasket Set for my scooter's routine maintenance and a small performance boost. The ordering process on the site was pretty smooth, I found exactly what I needed without any trouble. It took about two weeks for the package to arrive here in Florida, which is about what I expected for international shipping. Everything was well-packaged, no damage to the parts. The air filter was a direct fit, and the gaskets seemed to be good quality, no leaks after installation. The instructions weren't super detailed, but I figured it out. Overall, a decent experience, the parts are working as they should and I'm happy with the purchase for the price.
Good spark plugs
Bought some Spark Plugs. They fit perfectly. Engine runs well. Quick shipping to the US. No issues.
ECU made a huge difference
I got the Performance ECU for my scooter and wow, it's like a totally different machine! Installation was straightforward enough, and the power delivery is so much smoother now. I was really impressed with how quickly it shipped, too. Definitely shopping here again for more upgrades!
Consistent quality for parts
This is my third order from Yuminashi, and they're always reliable. I picked up a set of Yuminashi Performance Series Injectors this time, and just like my previous purchases of the Big Bore Cylinder Kit and High Lift Camshafts, the quality was top-notch. I appreciate that their parts consistently fit well and perform as expected. Shipping takes a bit, but that's normal for overseas. They've become my go-to for engine upgrades.
Got the variator kit
So, I decided to finally upgrade my scooter's variator and went with a Variator Kit from Yuminashi. The website was pretty easy to navigate, found what I needed without much hassle. Shipping took about 8 days to get to me in California, which isn't too bad for an international order. It made a noticeable difference in acceleration, definitely feel more pep. All in all, a solid purchase, no complaints.

what's their return policy like? just in case i order the wrong thing or something. performance parts specifically.
Hey, thinking about grabbing a big bore kit. How long does shipping usually take to like, California? Don't wanna wait forever.
Planning to upgrade my scooter, are Yuminashi parts generally considered good quality? Like, compared to Polini or Malossi?
Does Yuminashi ever do any big sales for Black Friday or anything like that? Want to get an ECU but hoping for a discount.
Do they take PayPal or is it just credit cards? Trying to figure out payment options.
