I use the extended or projected electrode in all my 2-stroke MX bikes since the '70's. High revving 2-strokes are brutal on plugs.
The electrode actually runs cooler as it is the the direct path of the air/fuel mixture, as opposed to the "shrouded" (regular) electrode.
Another advantage is more efficient burn with the electrode extended further in the combustion chamber.
