    Don't you look at my accountant.
    He's the only one I've got.

    The R7376 plug has an identical nose configuration to the stupid expensive shorty plug and cap for less than 1/4 the price.
    Its only difference is the insulator length , thus it uses a " normal " resistor plug cap.
    Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.

    But try putting the red one on a shorter plug.
    Works either way with the shorter one.

    So, i finally made a calculated pipe for my violated SGM Kartengine.(bored out to 144cc)
    Running on E85 i made the other day 48.2hp to the wheel at 12700rpm
    Depending on what is correct when calculating losses it is between 51,9 or 56,7hp to the crank(my dyno reports ~10% but some says it should be 15%.

    However, I ran an BR10ECS.
    The diskussion above about that expensive NGK plug, is it known to make any more power than 'normal plugs'?

    My plug and dynosheet, and below link to a livefeed when i was dynoing it.
    Dynosheet shows before and after testing with a no calculated pipe and a calculated in Mota.

    Very hidden spark Position i think

    Why not trying a cheap BR10EIx?

    And for a new pipe you need new ignition map to gain max out of configuration

    So there might be more lurking you say?
    Timing is as enginemanufacturer says it should be, now with 58mm bore it can make use of some more i guess.
    But i´ve got a lot higher compression also, to make use of the alcohol.

    My experience is

    If you use another pipe, ignition timing never fits to manufakturers advice... if you do only one change in complete engine system setup...you need another ignition curve that fits to new circumstances...

    2 strokes are bitches 😉

    Have good times with 😀

    Forgot to mention that from what i can see on the old sparkplugs timingmark, there isn´t much to gain, looks dam near perfect to me =)

    As i can see

    Your peak power rpm changed...👍 so you should change 15 degree ignition point to this....best using programmable and set ignition correct at new resonance beginning too...this is gaining much wider powerband

    I would not use an EIX plug if they were free.
    When run even close to deto, the ceramic shell around the center electrode would immediately crack, then fall of.
    Saw many, many engines killed by those bloody things - they are cheap for a reason.

    The dyno / track work has been done hundreds of times before, in many race engines.
    NGK R7376 Iridium - Platinum or the expensive shorty equivalent, simply makes more power and is way more reliable than any other plug ( including the ND Honda part number ) - end of story.

    The short body plug was originally configured for Honda racebikes with the front cylinder too close to the radiator, but in karting everybody uses them for extra elbow room
    plus of course the proven power advantage.
    Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.

    Powervalve operation, twin ports.
    How far round should the transfers come?
