XR600 spark plugs???

I was wondering if anyone has ever experimented with using different spark plugs in 600's. I use the standard NGK plug in my 642, but would a SplitFire or a platinum plug have a noticible difference?? :)

OK, if no one has opinions on plugs, then how should I go about getting a better/stronger spark to burn more fuel?? :)

Try a larger gap on the standard plug. I gap mine at .045. The larger the gap, the larger the spark. Learned that a long time ago.

Give it a shot. :)
