New Moto Guzzi Door Mats Available Now
The NGK caps fit over threaded posts at the tops of the plugs, not the brass tops that the original plugs have. It's harder to explain than it would be to look at photos in a parts book. You'd immediately see the difference. The plugs are the same - except at the very tops. The OE (original equipment) caps are not all that good. Better to change them when you can. I bought my bike from the previous owner you think you'll never meet. He had done all those "little things" so by the time I bought my V7 I could just ride it and not have to fuss.
