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.

A Amber J. 2 months ago

Returns were pretty straightforward for me when I accidentally ordered the wrong size piston. Just follow their instructions on the site.

I think as long as it's not installed or damaged, you should be fine. I'd double check their policy page for the exact timeframe though.

Hey, thinking about grabbing a big bore kit. How long does shipping usually take to like, California? Don't wanna wait forever.

D Dan 2 months ago

I'm in Florida and got my order in about 7-10 days, if that helps. They ship from Europe, so expect a bit of a wait.

B Ben D. 2 months ago

Yeah, they definitely ship to the US. Mine took about a week and a half to New York. Not super fast, but not terrible for international stuff.

Planning to upgrade my scooter, are Yuminashi parts generally considered good quality? Like, compared to Polini or Malossi?

J June Walsh 2 months ago

Definitely legit. I've used their stuff for years on my Honda, never had an issue. Performance is solid, always felt well-made.

T Todd A. 2 months ago

They're up there with Malossi and Polini for sure. I'd say they're in the same league. Focus more on Honda stuff though, if that matters for your ride.

Does Yuminashi ever do any big sales for Black Friday or anything like that? Want to get an ECU but hoping for a discount.

T Todd Torres 1 month ago

They totally do! I got my variator kit during their Black Friday sale last year, saved a good chunk. Keep an eye out around then.

Yeah, they usually have something around the holidays or for summer riding season. Performance stuff is usually 5-15% off, but OEM parts can be way more discounted sometimes.

Do they take PayPal or is it just credit cards? Trying to figure out payment options.

T Todd Whitfield 2 months ago

Yeah, I'm pretty sure they take PayPal. I always use it for online purchases there, no problems.

They accept a few different payment methods, but PayPal is definitely one of them. Super easy to use.
