Which NGK Iridium spark plug ?
The CR8, direct replacement ?
Or slightly cooler CR9 for modified units or “high speed” use?
What is high speed on a Ruckus ?
More than 50 kph ?
Usually ride 40-50 kph,
Except intervals of 15-20 min at 50 kph.
Which Iridium plug ?
Thanks !

Hi Corey, I still can’t figure out where the “crankcase breather” is located on my Ruckus! The link you provided me with the diagrams is great, but the diagrams assume the viewer already knows the location of it on the Ruckus. Is it at all possible to provide me with an actual photo of the “crankcase breather” on the Ruckus? Thanks for all your time, knowledge, and help.

Just to let you know thats not the right spark plug link for amazon. Atleast it isnt for my 2004 ruckus. It needs to be ngk r type

The reviewers on Amazon seem to disagree with you. Amazon also tells me “This fits your: 2008 Honda NPS50 Ruckus” with a green check mark.

Word of advice. If you bomb around at full throttle a lot, you should use an NGK CR9EH-9. It is one step cooler that OEM. I found the OEM plug insulator was a bad white colour (indicating a too hot condition) I went with the aformentioned plug and now the insulator is a nice tan colour. This is with regular octane gas.

I was told my 2015 ruckus uses a different spark plug then most of the older ones. So which one is it I need?
