Good product, reasonable price, all around satisfactory.
This jet worked great. I'm no expert, but I think the dimensions are spot on and the finish/machining is at least as good, if not better, than the original jet that came in my Mikuni carburetor. And I think the price point is perfectly reasonable. I am satisfied with this product.
Made some mods to a TTR 125 and needed to do some rejetting. Bought several sizes to cover different conditions. Don't be sceptical about buying these aftermarket jets. They are just as good as OEM and a fraction of the price.
