Could anyone reccomend some jetting specs for my bike?
Its standard apart from FMF rear muffler, and v force moto tassinari reeds in it.

I have no idea what is in there at the moment, but keen to have a look.
Hasnt been fouling plugs regulary, but they are coming out pretty black.

On this chart here, they would be closest to the dry fouling picture

Should also add I am running NGK BR8EG, or BR8ES when I cant find a EG.

probably best to try US forum like DRN.net. RMs I'd use the specified plug as vibration kills std plugs & drops tip into engine. Used to be a problem one the earlier ones, not sure about 08s.
