 Re: spark plug qustion
A NGK B6HS will perform exactly the same, IMHO. A B7HS may as well IF you are not running too rich (air/fuel). (Each number higher with NGK is a step cooler plug). I'm running a B7HS now. It was perfect for several months. My fuel petcock broke, and I changed a few fuel and other things - now it's running a bit rich (I can feel, smell, and see it) and my plug is not doing so well. I changed the fuel clip last night....but we were (and still are) having a thunderstorm so I have not ridden it yet. |
