Hello Guys,

For my XS650 - should I be using regular spark plgs or are there high performance versions that are worth getting ?

Cheers

Mick

NGK B9ES are one heat range colder than stock and I was told by a much more experienced plug-reader than me that the B8ES were too glazed (too hot) to get a good reading.Never had a spark plug issue with them.Available at auto parts store.Never tried the Iridium plugs praised by MikesXS and XSDirect.

Gary,

Thanks for the info.
Will you be at the Quinte TT in June ?

Mick

I plan to be.Signed up yesterday.See you there.
