    Stick with the BR8ES-11's. Sounds like your a little lean on the low end. Have you tried to richen it up a bit?

    I have quite a few stock head/compression skis performing well with the Iridium plugs. I am with GPR FL, you sound lean in the accel circuit.

    Do you have a controller? If so open up #2 a bit.

    I use the BR8EIX Iridium plugs. They work fine. I used to use the BR8EV's (gold plated), but they were discontinued NGK decided to go with Iridium. I am of the opinion they gaveme some rpm's on top. I posted that a long time ago about the BR8EV's and about got ran out of town.

    I had a similar reaction on a forum when i found the champion 8902 spark plug. It has an extended wire tip like the iridium plugs, and its only 2 bucks a plug at your friendly wal mart here. Oh yea, it also happened to give a measely 100rpms on my seadoo 951, and a noted increase on my gp1300 also, but still with the factory tach i cant claim the actual rpm gain, but its there. You can actually hear the difference in the engine, even at idle..
    Lighting the fire in the center instead of right on the top of the mixture in the cylinder seems to help... I guess the correct terminology here would be (the positioning of the flame kernel) created by the spark plug electrode sitting down lower in the cylinder head by approx 1/8 of an inch,, Try it guys, youll like it...

    To All GpR Enth.

    The ski is Curently equiped with STAGE II and VF3 Reads.

    VFO i do have EFI. and the settings are 6,4,1,6

    What i think is The BR8ES-11 Doesnt Have enoght power to burn the mixture.

    i experience the same problems when i used to have 2002 GP1200R and used the NGK BR8ES.

    Please Advice

    I just got through troubleshooting what I thought was a plug problem. I was thinking the same logic as not enough spark to properly ignite the fuel. I moved to NGK BR9ES's. Went out this weekend to test them and still had a hesitation when I would pin the throttle. In fact, it was getting worse. Decided to take it to the beach and pull the #3 plug. To my surprise the plug was solid white, extremely lean. So I pulled #2. Same thing, very lean. So I started checking through my oil and fuel systems. Then I saw the problem. The ground wire had snapped off the EFI cotroller and I was running on my stock fuel map. I was dangerously close to seizing! So I repaired the ground, dialed her in and went back to my BR8ES-11's and it ran like a champ the rest of the day. Check your controller!!! One little wire can cause THOUSANDS in damage.
