Hi guys, just crossed my mind that I have never checked if I am using the right plug in my sx, it came with a couple of spares and I've just fitted them and ridden but am I using the right one?
I have an sx 150 with a mugello 186 kit, 28 mil phbh open mouth and a vw reverse cone . Any idea of which one is the best one, around town and localism rallies up to 60 miles each way.

Just checked and it's a B7 ES I'm using at the moment, what is the difference.

B7 is to hot for what you want, their ok for running an engine in but your asking for trouble using one to do rallies etc on, B8 good all rounder, B9 for sustained high speed, motorways etc.
Personally I've just started using a B9 for all my riding as I don't do pottering around town much.
I have heard that a B9 won't last as long as the others so we will see.
