Brownish exhaust smoke

Went for a couple practice sessions yesterday on the ice track. Pulled into the pits and a buddy asks what Im running for premix. I say Dominator, why. He says my exhausr smoke is light brownish. So I start up the she and sure enough its brownish exhaust smoke out of the silencers. So I rip my buds new KTM 250r for a couple laps, then drink a couple beers. Fire up the shee to load it up and exhaust smoke is normal. Tranny fluid is a little low, just a tad. Radiator is full, resovoir is on the low mark, it was halfway between full and low if I remember right, just installed an aftermarket radiator last week. Doing leakdown test now, holding 6# for the past 15 minutes.

Every single one of the heaps ive bought over the years needed the packing replaced the day i brought it home. People never think to check that, id start there as you were advised.

This. I've never gotten a bike that someone has mentioned changing it. I've had cores rattle from being completely gone. But never a bike that has had freshly packed silencers.
