Simple question on the plugs...

What is the proper gap? I have carbs not FI.

I see all kinds of charts on other sites, I just want a simple number to set my new plugs at...

Thanks

Question: Can i do better then the plugs that came with the bike. Im a Autolite double platnum user for my car.

Not really. Some don't wear out as fast (platinum) but the NGK's that came in your bike are fine.

if Doc says they're fine that's good enough for me

Don't forget rec'd too!!

I went by the parts store this morning to get some rec'd plugs...they were all out....said they had a run on them last night around 8:30 for some reason.

They heard it first right here on Kawanow ;)

BD,
Speaking of spark plugs, Seems like I've read that cooler plugs may help reduce the " pinging" we are all familiar with. It makes sense that cooler plugs would reduce pre-ignition. What are your thoughts?
Thanks

I used to think that in theory that might have some merit, but I'm inclined to not believe it. I went from 6's to 8's NGK's and didn't notice much of a difference other than the 8's were much dirtier when I took them out. I believe each manufacturer uses a specific plug for many reasons.

Think about it for a moment. Wouldn't we all use colder plugs in all of our vehicles that called for premium if it meant we could use regular? Why wouldn't the manufacturer install them in the beginning.

My understanding is that plug design is made with a big consideration to what temp the plug needs to be to burn hot enough to keep the plug clean.

Then there is pollution considerations on why this heat range of plug is used and not others.

In my racing days, we'd run the coldest plug that would fire in our drag bikes. Running WFO for the quarter mile put enough heat in the bike to run ok. these plugs were so cold that if we "idled" back to the pits they would carbon up and foul out.

good point. oh well.

Thinking shows your learning to try new ideas which is great! don't stop trying to solve some issues on your own and share. That's how we all learn. Well........almost all..
