Hey guys just picked up a 2013 KTM 250 sx. Noticed the plug was burning black. The guy was running 50:1 and I'll be running 40:1. My elevation is 3661 feet I've got a Suzuki needle on the way but need help with the jetting side. Always rode four strokes and never had to jet them. Thanks in advace

Try 32:1 or 40:1 with a 40 pilot, the RM 250 NECJ needle on the 3rd setting and a 172-175 main jet.
