    For our Canadian members I just came back from the local Crappy Tire store. I went to pick up some BP7ES plugs. Guess what they no longer carry them they said I could use BPR7ES instead!!! 8O I said NO you cannot!!!. :evil: The local Crappy Tire is not even allowed to buy direct in order to have them in supply. What a bunch of bull sh*t. They told me to change my plug caps, NO!! :evil: I want to keep things as stock looking as possible thank you.
    Fortunately we have a local independent Biker Guy who has a small shop and I can get them there. :D
    END of RANT!!!!!!! :twisted:

    I had the same problem with the NGK BP7ES plug....And when I called the NGK Tech line, they told me they were no longer available in Canada, and any that I did find would be old stock. Len can still get them!

    Please call NGK and see If you get the same info...they told me to use the BPR7ES plug and close the gap 5 thousands!

    The problem with using the NKG BPR7ES is that they are a resistive plug which means that in oder for you to use them we have to remove the stock plug cap and use a automotive cap. You see the BPR7ES ADDs 5 ohms resistance to the coil wires which in turns weakens the spark and WILL cause the bike not to run right, miss fires due to POOR spark.

    Actually it doesn't weaken it as much as change the duration; but they don't need the extra resistance, that's true.

    I think the book has an ND plug (Denso) listed as an alternative; has anybody tried them yet?

    Don't bother with Champion N7YC's; my Norton runs those. But I use BP7ES's to get it RUNNING first, then swap in the Champs. Even a set of new Champions has a hard time firing the bike after seasonal layover but it always lights right off with a set of (used even) NGK's.

    I have had a look online and while it is not as easy as getting them
    from a local store you can order and buy BP7ES off the net.

    Back in '03, when I bought my Audi, I bought expensive platinum Bosch plugs, then ND's...they didn't last. The smartest guy (I think) on the Audi Forum with the same car, suggested I try the Autolite equiv. They perform awesome and last forever. Compression is 11.5/1 and it rev's to over 6500 - - tuff on plugs.
    I see Autolite has 2 possible replacements for the BP7ES. Check 'em out:

    I wouldn't be afraid to use Autolites.
