    hey... try the NGK iridium sparkplugs...... they are more money but WELL worth it...... i run them in my R as well as my cobra and vette... and made a world of difference..... you have to run br9eix... im pretty sure thats it.. i will double check 2morow... hope this helps.

    Ive always gotten the brightest spark w/ the plug he's running, I say stay w/ that range plug and jet a little better, most of those hi-$ plugs take a chit easy and are meant to be replaced every couple moto's, just my opinion...

    also try closing your plug gap if your running the stock iginition. Try 18 to 20 thousandths.
