This carburetor made my KX450F start and run smoother instantly. Simple to install, and the throttle response is crisp now. A reliable OEM-style upgrade.
This AFM disabler works exactly as promised. My truck stays in V8 mode, eliminating the annoying lag on acceleration. Easy plug-and-play install. Might lose about 1 MPG, but for the smoother drive, it’s totally worth it.
They look very good and seem durable. I have assembled them well; they don't fit 1000% exactly but for the price, more than enough, I would buy them without hesitation.
The product arrived quickly and safely. I am very satisfied and highly recommend it.
Excellent quality, better than expected, easy to assemble.
The product works well. I had some issues connecting the cables and contacted customer service late at night, on a holiday. They responded and explained how to connect the cables, and everything was great. I highly recommend it.
