    I did use them. And I forgot what the problems was. And it was before I found out about the dude that dynoed bikes and talked to Thunder-Max and found out about the interference with them.
    And I was told to use the standard 4164
    Thought I posted this.

    I put in a pair of SE 32186-10, Manufacturer calls for .035 gap. I gapped at .033 added a proper amount of lucus octane boost to 91 octane gas, run the bike pretty good, stop,get in it and get, then stretched it out a bit, approx 50 - 60 miles. Tail pipes looked good, pulled the plugs, looked good with a slight light tanish red color that octane boost leaves. Gonna try some autolites next time just for curiosity.

    I have a pair of e3. 36 spark plugs. I hear they are a waste of money? I also hear they work good with big bore motors. 135 hp/136 tq. Have anyone experienced these plugs or have opinions? I haven't tried them yet.

    Since you have a set and you've been trying out a few different types,screw 'em in and let us know if you feel a hp/tq difference:). My opinion on the high dollar exotic plugs is, they are a waste of money. Once the plug ignites the compressed air/fuel mixture....it's job is done...The only benefit from them is they'll last longer and you might get quicker starts.
    A good standard plug(pick flavor) in the right heat range is all you really need.

    They sure are different looking plugs...I remember hearing about racers indexing the plugs pointing the open end toward the intake valve so ground strap wouldn't shroud the flame to try to shave off .001 seconds, don't know if it really worked though:D
