Anyone got any suggestions re jetting, curing plug fouling? I haven't ridden it yet but bought from a mate who tells me it does this sometimes. It has new top end and the old piston had a lot of carbon on the crown.
"does this sometimes" sounds like one of the circuits is rich. i had a kx250 that would foul a plug after long v. slow downhills, where it was just idling so leaned up the pilot jet and problem sorted.

you will need to try and find out which circuit is off - start by checking the jetting database for similar bike and conditions
