    What spark Plugs do you run?

    I bought a 1981 GS 750E about 2 weeks ago and I am going through the maintenance to be sure everything is good. In the owners manual, it specifies to use a NGK B8ES spark plug. The plugs that are in my bike are Champion RA6HC. I didn't like seeing that so I bought new plugs today, B8ES, and I am going to install them tonight with a .031 gap, per the owners manual. I am curious as to what other plugs are being run in stock bikes, and what kind of results others have had using different plugs. Thanks for sharing!

    Plain spirit of dead ancestor fearing NGK as specified in the manual.
    Fancy plugs are a scam like ***** enlargment pills.

        My '82 1100E uses a D8ES spark plug.

        I just use an NGK spark plug, which is stock.

          My mistake...for some reason I had that B8ES in my head. It actually is a D8EA. Rookie mistake!

            Oh yeah. It's actually a D8EA for my bike too. Not D8ES .

                They put ngk in at the factory so I don't think you can go wrong with them. Alot of drag racers used autolite plugs back in the 90s don't remember the number but I think they worked good. I have always used ngk a haven't had a good reason to change

                  I run the iridium equivalent of the stock NGK plug in my 300. Runs very nice.

                  The... DR8EIX, if I recall. Not one of those annoying fancy "multispark" things, just a smaller electrode for a more controlled spark location, and a harder electrode for a longer life.


                  Edit: Ah yes. What posplayr linked. Very nice stuff, I'm quite happy with them.

                    Hi,

                    I use flux capacitors.

                      The B8ES is used in the big 8 valve bikes

                      I've used NGK, ND, Champion and a few others over the years

                      Never noticed much difference

                        I would like to use flux capacitors as well, however my bike was built 5 years before Back to the future. Is there a writeup somewhere on your site? Mcfly?

                          I use NGK D9EA in my bike. It helps the engine run a little cooler.
