br9es vs br8es

[noid]

Which one would you recommend for a blaster? Its bored by .80, has a fmf gnarly pipe, and a larger carb then stock (not exactly sure of exact size).

Also what should the plug gap be?


Its a freshly rebuilt topend (new gaskets, same piston)

The B8ES, the B9ES is COLDER!, you'll probably foul it out, your engine doesn't have enough modifications to warrant the use of a colder plug.

deff. br8es stock gap is .028-.032 so I'd probly hit around 30 it will probly varrie with your climate/mixture and such.

I will be riding it during summer at a range of about 25-35 celcius. At a mixture of 32:1 with amsoil.

Also forgot to mention that my motor is ported and polished and i have a boost bottle.
