    I used the B6HS for several years on all my 2-strokes. Great all-around plug, IMO.

    NGK B5HS works well, and a BP5HS, which is extended tip, works a little better for me. A 6 is a little cooler plug. They work well too

    It really depends on where you live. Yea right, your thinking. The thinner the air the "hotter" the plug needs to be. At Sea level the B6 HS is fine. The numbers go down, the heat goes up.

    I purchased two NGK B-6L plugs at my Canadian Tire store Feb 27/2012. I installed one on the bike's motor. I am waiting for the summer of 2012, hoping that this BGF 66 CC gas engine won't let me down. The instructions for this motor say to install a NGK BP-6L if you can find one. Otherwise, install a NGK B-6L, as I did. And if this can't be found, go for the NGK R7-HS.

    I can't tell anymore, but think The Letter L means long thread. It's a winner if you want to put a sun roof in the piston.

    B7hs is the median. B8hs is a cooler spark. B6hs is a hotter spark.

    Use B7hs. It should be good
