Customer Reviews
Good parts, slow shipping
I purchased a Yuminashi Performance Clutch Set. The quality of the clutch set itself is really good, feels durable and performs well since installation. However, shipping took a bit longer than I expected, around two weeks to arrive here in Texas. I wish they had faster shipping options or at least more accurate estimated delivery times. Customer service was responsive when I inquired about the delay, which was a plus. Overall, a solid product, but be prepared to wait a bit.
Reliable as always
This was my third time ordering from Yuminashi, and they didn't disappoint. I picked up a Performance ECU this time. Just like my previous orders for Big Bore Cylinder Kits and a Racing Crankshaft, the product arrived well-packaged and exactly as described. Their consistency is why I keep coming back. Shipping was prompt, taking about 7 days to reach me in California. It's good to know I can count on them for quality parts.
Smooth order, good support
I ordered a Yuminashi X-Series Wideband AFR Gauge Kit a few weeks ago. The ordering process on their website was straightforward; I found what I needed without any hassle. Shipping to the US took about 8 days, which was reasonable for an international shipment. I had a question about the installation instructions, so I contacted their support. They replied within 24 hours with a clear explanation, which really helped me out. The gauge itself seems to be of good quality, and it's working perfectly so far. I appreciated the clear tracking information provided.
Got my parts, all good
Just received the High Flow Air Filter I ordered from Yuminashi. Everything went smoothly. I needed a new filter for my scooter, and this one fit perfectly. It came in good time, maybe a week and a half, so no complaints there. Pretty happy with it, honestly. My scooter feels a bit zippier now.
Parts arrived, good quality
Ordered some Heavy Duty Valve Springs. They came well-packed. Took about ten days to get here. Seem like good quality. Fit perfectly. No issues.
Absolutely amazing pistons!
I just installed the Yuminashi Forged Pistons in my bike, and what a difference! The power delivery is so much smoother, and the engine feels incredibly responsive. Ordering was a breeze, and they arrived quicker than I thought for an international shipment. I'm so impressed with the quality and performance. My friends are going to hear all about this, I'm definitely shopping here again!

Share tips, ask questions & help fellow shoppers save more
Hey, I'm looking at getting a big bore kit for my Honda Ruckus. How long does shipping usually take to California?
Does Yuminashi ever do any big sales on their performance ECUs? Kinda pricey.
Thinking of picking up one of those X-series wideband kits. Are these generally considered good quality compared to, say, Koso or Stage6?
What's the deal with returns? If a part doesn't fit or I change my mind, is it a pain to send back?
