Honda-SOHC

There are a couple of diferent posts about that recently on the US forum Ash, what they say makes sense to me in that a running prototype would be there before a pre full production set sent out to tease the dealers but not sure about Honda leting that out of the factory first

Ted, if you can find any D7EV are the dogs doodads for the 500, it should have had newish D7EA in it when you got it, D7ES is the original and not available the A is same as S according to NGK. You should not be using the R type

So far nobody knows. Why did you choose 'R' plugs?

I have no idea when or where I bought them - I have a set of new NGK DR7EA plugs.
DS show the 500 plug as NGK DR7ES.

Can I use these DR7EA no idea what the S means compared to A ?

Sorry to hear you are understandably down at this time Bryan.
Many of us heading for the cliff, but look inland and hope you will find solace in another direction.
I sure you get satisfaction helping online mates here.
It's over 20 years since I went online looking for advice and you were there back then. Can't remember how I found you but it was before this forum I'm sure. Keep on keeping on.
