Customer Reviews
Good quality and excellent savings!
The discount code saved me a good amount on my new Connecting Rods. The parts are high quality, just as expected from Yuminashi. I was hoping for an installation manual to be included, but it wasn't. Still, it's a solid purchase and I'm happy with the price I paid.
Decent value, slight delay
As a first-time buyer, I was looking for the best deal on a Racing Crankshaft. Yuminashi had a competitive price, especially with a small promotional discount they were running. The checkout process was smooth enough, and they accepted my usual payment method. Shipping to Florida took a bit longer than I expected, around two weeks, which was a minor annoyance. The part itself seems well-made, and it was worth the wait for the price I paid. I'd consider them again if they have another good offer.
My scooter flies now!
I got the Big Bore Cylinder Kit and a High Lift Camshaft for my scooter from Yuminashi, and I can't believe the difference! My ride is so much faster and more responsive now. Everything fit perfectly, which was a relief. I'm telling all my riding buddies about them. I'm definitely coming back for more upgrades for my other bike!
Solid upgrade, good support
I recently bought the X-Series Wideband AFR Gauge Kit from Yuminashi. The ordering process was simple on their site. The kit arrived in about a week and a half, well-packaged. Installation was pretty straightforward with the included instructions. I had a question about connecting it to my existing ECU, so I sent an email to customer service. They got back to me within 24 hours with a helpful, clear answer. The gauge itself works perfectly, giving me accurate readings, which is crucial for tuning. The quality of the components seems high. My only small criticism is that the product images on the website could be a bit clearer with more angles.
Good performance, some shipping quirks
I ordered a Yuminashi Performance ECU for my scooter and overall, I'm happy with the upgrade. The power delivery is much smoother now. Shipping took about 9 days to get to my place in Texas, which felt a little long, but it did arrive safely. The website was easy to navigate and find what I needed. I just wish there were more detailed installation guides available directly on their product pages.
Fast shipping, great part
Got a set of Yuminashi Performance Series Injectors. They arrived quickly. Installation was straightforward. My bike runs better now.
YUMINASHI Community Discussion
Share tips, ask questions & help fellow shoppers save more
Thinking about getting some parts during Black Friday, how good are the discounts usually? Like for performance ECUs or variator kits?
Does Yuminashi ever do any kind of free shipping deals, especially for bigger orders like a full exhaust system or something?
Anyone know if Yuminashi parts are actually good quality, or are they like some cheap knockoffs? Kinda wondering about the 'legitimate brand' thing.
Can I use PayPal to pay for my order, or is it just credit cards? Couldn't find it easily on their site.
Hey guys, thinking of grabbing a big bore kit from Yuminashi for my scooter. How long does shipping usually take to the US, specifically California?
