Drop your needle one clip. Plug won't make any difference, but it should be a br8. Iridium last the longest for me.

Depending on the temperature differential you may need to richen across the board.

Just so I make sure im understanding your advice you mean raise It one clip so it drops lower? I.e. the higher the clip position the leaner it is?. I have pretty much same jetting as above tiny spooge but fouled a plug last ride. Wondered if im to rich. Gone for the irridium plug this time br8eix i think it was

Make the needle lower, this reduces fuel where you use the throttle most and are likely experiencing problems

thanks was just making sure I understood correct. i.e. I need to move the clip up one notch to drop the needle down. ive got the JD blue needle but might try the N3eg ive also got

N3EG changed my bike completely, 2nd or top clip.

On my 300 2008 N3EG was too rich on 0-1/2,and too lean after that. And the best position was 3.if I was moved up or down become worst. So I took N3CG @4 spot on!!!
