Gaping Sparkplugs
How many of you out there use gaped sparkplugs? I am having high RPM breakup and I have read several threads where people recommending using gaped plugs as a cure but I just wanted to get another opinion on it.
Thanks
Thanks

I've been using gapped NGK B10EGV plugs for a while. They do seem to reduce break-up at high RPM for me under high boost. You need a thin-walled spark plug socket to install them. They are not surface-discharge plugs, so you can adjust the ground electrode to set the gap. I have read that they reduce power slightly versus surface-gap plugs, but if you get break-up with the surface-gap plugs and don't get it with the B10s, it would seem to reason that you will get more power with the B10s. I have been too thrifty to spring for the NGK rotary racing plugs yet.
B10EGV plugs are less than $10 each (I think I paid $5 or $7).

I think mine are the same that Max is running.
I'm running 10's all around and you need a very thin wall socket to change them. You should be just fine will all 9's unless you're heavily modified.
I have to get the 10's from a motorcycle shop.

I got mine from a local motorcycle shop, too. That was an interesting conversation.
They still had to special order them, but it didn't cost me anything and I had them in a few days. I think I got some from sparkplugs.com as well.
There is an Iridium version with an X in the part number that might be worth a look, too. B10EIX might be that part number, but that is just from memory -- I am not sure it's right.
