Used this kit to rebuild my 2008 YZ250F, and it was exactly what I needed. Cylinder and piston fit perfect, and now the bike runs better than ever. Solid quality parts for a good price—definitely recommend for anyone doing a rebuild!
What really sets this top-end rebuild kit apart is how efficient it is. It’s designed to cut down on the time and effort needed for a rebuild, saving you both money and headaches down the road. Plus, it includes clear, easy-to-follow instructions that make installation a breeze.
Not bad for the price. I already had a piston and rings that I bought independent of this because I knew the top end needed to be fixed. When I took the engine apart, I found the cylinder was scored and needed something in 5 days for a trip coming up so I rolled the dice. I measured the milled surfaces and the cylinder bore and found that it was surprisingly decent. I bolted it up and put on 8 hours on the machine. So far, no leaks, no cracks, good compression. I'm shocked that something this cheap actually held up so far.
I was impressed by the quality of this rebuild kit. All the parts fit perfectly, and my machine started right up after the rebuild. Runs strong and feels brand new!

Do its job well

Super high quality design and craftsmanship pricey but its worth it trust me

Perfectly fixed the issue of the horn sometimes not working and the warning light staying on all the time.

Beats paying for OEM carburetor

Perfect!

This seller is awesome—their stuff is top-notch. I bought 30 from them before, and only one didn’t work out. I tried another cheaper place and got 50, but at least 15 customers complained they were either useless or failure after a few days. Compared to that, this place is way better. You really get what you pay for. This time, I went all in and grabbed 100—should keep my shop stocked for about two months. Definitely coming back for more when I run out!

Showed up right on time, and the communication was on point the whole way through. 100% would buy again! The grill quality is seriously top-notch.
Highly recommend getting a body shop to install it—there are always little tweaks needed for a perfect fit, especially with the crash bar and sensors. In the UK, you can’t remove the poly padding on the crash bar, so keep that in mind.
Definitely ordering again—looks straight-up classy on the car!

Real solid quality, especially since I couldn’t find it anywhere else. Glad I got my hands on it!

Superb quality. Thanks

The carburetor fit great and started right up. Great buy.

Great carb !!!! Never let me down. Great service from champoo once again. First Class 👍

As good as OEM

My car basically just quit on me—totally stopped moving—and the codes were pointing to an O2 sensor failure. Thankfully, the upstream and downstream O2 sensors I ordered showed up super fast. I bought both just to be safe, but I only needed to swap out the upstream sensor right away (along with some new spark plugs and a MAF sensor I grabbed from another place). After the install, my car’s running smooth again, and that annoying check engine light hasn’t come back. I’ve bought a bunch of parts from 1A Auto before, and honestly, I’ve never had any issues with them. They’ve been solid every time.

My order arrived right on time, no delays at all. I got it installed the very next day, and let me tell you, it fit like a glove! Now I can see everything clearly behind me while I'm riding—no blind spots, no stress. Honestly, I couldn’t be happier with this purchase. It’s exactly what I needed, and it’s made driving so much smoother. Totally worth it!

Fit well and perform well
