New Honda Ruckus owner.
Going to install a tachometer.
While I have the "hood open" to wrap sensor around spark plug,
Planning to replace stock spark plug with NGK Iridium plug.
Appears there are two models...
Standard and high performance.
High performance plug is for modified units or extended high speed riding.
Not planning any engine, CDI or variator modifications.
What constitutes high speed riding ? Above 50 kph ?
I often ride at 50 kph for 15 or 20 minute intervals.
Which plug ?
Thanks for your feedback!
