Spark Plug Suggestions Anyone?

I'm going to pick up some spark plugs for my 86' vn750 today and was wondering if anyone had any brand/type suggestions along with their part # so i can just head to autozone and pick up a set.

Thanks! and happy Friday!

X2 with Swagman ! Better - Easier starts and great/improved performance ! Be aware, you will need to remove the little end caps from your new plugs.
Enjoy

We all know I'm a total dork right? Good. Iridium trivia: anyone know where iridium came from? It's not indigenous to our planet. A gargantuan iridium meteor crashed here 65 million years ago and kicked up enough red dust into our atmoshspere to block out the sun. No sun - no plants, no plants - no herbivores, no herbivores - no carnivores. Iridium ended the dinosaurs...now its in our spark plugs. LOL!!! That explains why it's so expensive - VERY limited supply...

Be sure to pick up and use some spark plug anti-seize compound--& apply this to your new spark plug threads b4 screwing them in.

It's also a good idea to use some compressed air to blow out the spark plug recesses in the cylinder heads, before removing the plugs. Sometimes, you'd be surprised at what is waiting in there to make a new home inside your engine!

Also--there's a special socket that came with your bike's tool kit, that fits the taper of the spark plug locations, specifically for removing and installing spark plugs. This will be easier for you to use than a regular spark plug socket. If you use a regular spark plug socket, you may have to machine it some to get it to fit in the recesses properly.

Iridium plugs require less juice to fire (& so less work for your bike's ingitors), and stay clean/gapped A LOT longer than regular plugs. That's why they're worth the extra money, as recommended above.

All this should make your spark plug swap A LOT easier.

I don't know where you got that idea about the iridium on earth coming from a asteroid. Not true. Some iridium came that way, but certainly not all. Better check your facts again. Of course you could claim everything on earth came from someplace else and be technically correct. You know there is something that has always bothered me about the asteroid killing all the Dino's theory. If they all died around the same time, why airnt there massive piles of bOnes at the K-T boundary ?
