and this one...
The plugs dont look much different and the only reason I know they are out is by the bikes performance and as soon as I replace them with new ones we are back up and running.
I have to change my plugs about once a month because they burn out. I have tried just about every brand of plug that matches the NGK and have had the best luck with champions but they still burn out a lot. Any suggestions on different plugs?
