Default what spark plug with mthese mods

I have a 2001 raptor and am rebuilding because of the tranny. I did a 1mm bore and bought a wiesco 11:1 piston for it (oiston and sleeve were scored) and i also bought a stage 2 web cam with the valve spring kit, i am going to work on the jetting soon. And my friend brought up the question if we need to run a cooler spark plug or something. He is rebuilding the quad and i am helping so hes the brains [img]i/expressions/face-icon-small-happy.gif[/img]

I have a raptor with 11:1 piston and the stage II cam, open air box ect.. I ended up running one step colder on the plug to get rid of the white on the ground strap. I'm running 25 pilots,190,195 mains and needles on the 3rd clip. It worked well for me but everyones diff.....

Dyno Jet needles and Mikuni Jets. I used them cause they were smaller and I needed more fuel.[img]i/expressions/face-icon-small-cool.gif[/img]
