Spark plug color

This is how my sparkplugs look like:

No idea how long they have been in there.

K&N filter was already fitted and yesterday i drilled out my original cans like so: http://trx850.motomaniac.net/forum/view ... f=6&t=3130

My thoughts where that the spark plugs are a bit to 'dry' and now with the cans opened up I guess it will run even dryer! do I need to adjust my pilot screws?

Standard the screws are set at 2 turns, hayens suggest 2 1/2 turns. What gives a more rich mixture? 2 or 2 1/2 turns?
Where are the pilot screws located? behind the floaters?

fine but old...............stick some new ones in.

don't believe anything in the Haynes manual unless you get it confirmed from somewhere else. it is full of lies/bollocks.

pilot screws - Yamaha manual states 2 turns out, and is correct. If you set them to 2 1/2 turns out with standard jetting, needles etc it will pop and fart really bad. Dynojet spec 2 1/2 turns out with their kit and it's fine.

There supposed to be grey. Even the Haynes manual gets that one right.

Being old, and the eyes not being what they were the plug in the pic looks grey to me.
