Hi scooter folks, I wanted to know if anyone has an opinion on switching the stock spark plug for a platinum or iridium one. I use NGK platinums in the car because they last longer and work well with cdi ignition. Since plugs in scooters are easy to change and need changing more often, is there a performance difference?
-
Very good question. I've been wondering the same thing myself.
-
Of course you can... and you're are right bigblue on the long life thing... premium metals last longer than your traditional copper...
-
You could, but why? Spark plugs are cheap. Personally I would use the original and replace it when necessary. YMMV

Yup, why... I did not... I still use the copper electrode and change it when necessary.. ;)

Doesn't iridium result in better Preformance ?
-
That is exactly what I am asking about. I know that the Iridium plugs last longer(good in applications where it is difficult to change) but do they give improved performance? Would one expect better mileage, speed, smoothness? ???
-
iridium plugs do perform better , but on a well maintained properly functioning motor you may not be able to detect any noticable difference . It will start easier and the plug will last much longer . I have been using them in all my vehicles and think the small extra expense is more than worth it , especially in a single cylinder application . Good luck .

That's the first thing I did to my scoot. The fine wire arc's over sooner
so advances the timing 1/2 degree or so. It's only a little but adds a tiny
bit of power. The bike runs smoother and gets slightly better mileage too.
They don't wear out hardly at all so just pop it in and forget about it for 10
years or so...
-
Everybody's right... it's more on the long life thing... ;) But of course, manufacturers have to focus on "POWER" or "PERFORMANCE" to get the consumers attention..
-
Many thanks for the opinions. I will probably switch to the iridium at next service and give it a try...Len

Do check your spark plug once a year so it will not freeze to your alum. block & if you put the scoot up for the winter a shot of oil in the cylander is good,.
300i dt. givi top box, givi side boxes, admore lights,. hid head lights, home made rack for the givi boxes,. battery lead for charger, good for jump start too,.

I was under the impression that anti-seize is made exactly for that. Also I believe denso plugs now come with an antiseize coating on the threads.

Yup....

I Just bought an Autolite plug (at Carquest) that is a direct replacement for the CR7HIX NGK Iridium plug and it cost me a whole $2.21 with tax. That's less than 10% of what the NGK goes for. Just thought I would share the news. JOB

Sorry the number for the Autolite plug is #4194. JOB

Don't forget a spot of anti-seize on the plug threads early in the life of the scoot to prevent the aluminum threads following the plug when you remove it. Learned that from an old-timer airplane mechanic.

You guys are a hoot, and I don't even have a scooter yet! I love to tinker - so will be looking under the bonnet of this thing when I get it home from the showroom. Also know enough to know I don't know squatt about vehicles, so I'm not too dangerous....Spend a lot of time looking at my Scion engines, then wipe them off and leave them be.
