B8ES is the standard plug.

Why are you running the B7, which is a hotter plug?

The hotter plug can be used if you do a lot of short-trip riding around town, where the engine doesn't really get up fo full operating temperature, or you can use them if the engine uses a bit of oil and you need to have the hotter plugs to keep them clean.

On an otherwise well-tuned engine, the hotter plugs might actually get warm enough to glow and light the mixture before the spark fires it. This can lead you to thinking that you "need" higher-octane fuel.

The P in the plugs you suggested indicates a projected tip. Not sure if there is enough room in the combustion chamber for them. If there is, it would be OK, but I would still go with the BP8, rather than the BP7.
