Only mud and grease. The mud was from when I blew my bike up. The track was a red clay sand mix and I was so mad when I got home that I tore the bike apart and forgot about my uniform for 4 weeks or so. The other was grease. I rode my bike last weekend for the first time in 3 months minus break in rides and the first thing it did was foul a plug. So got it taken apart only to find out the girl who was with me left my spare spark plugs at the house.(she picked them up from the cycle shop for me bc she lives 5 min away and I live 35. They were supposed to be in her purse. Well bc of that I used break clean to try to clean it off and the oil/break clean got all over my jersey.
Those sound like some fun race days

Hey if it makes you feel better, I know a woman who lost her plane tickets to Canada. No shes not related... Thankfully.
Lets see what other great stuff have I used.
Of course. Oneal Element gloves. These things are cheap. I mean cheap. But you know what? They beat the $40 fox dirt paws that I originally got by a mile. The Oneals are comfortable, durable (relatively) and airy. Good product.
OZtrail camel back: Hard to the core. I had a pretty sick Chad Reed style endo crash a while back and this thing shrugged it off and asked for more. It wasn't even expensive. Its comfortable, not encumbering at all and I can fit 2 reserve bottles of water in there too. Really nice. If nothing else, check it out for being indestructible.
Scott racing hand grips: I had these on my fooper and WOW. My gloves never slipped, not when smothered in black soil mud and not when they weren't probably dry after a wash. They look sweet and are very durable too. I was a crap rider on the fooper before I went to a 2 stroke so I stacked even more than I do now (hard to believe right?). But they were good to go after every tumble. Good stuff.
This ones kind of intermediate but I'll throw it in anyway: Haynes YZ manual (1986-2006, I think, don't quote me on that). Now its good, step by step instructions. Don't get me wrong on that its a hell of alot better flying blind. BUT: it will occasionally refer you to the chapters technical specifications to turn a screw in our out the x number of turns. The x number of turns isnt in the specs. Annoying. I'm absolutely sure I'm doing it right too. But hey, heres someone writing a whole how-to book on several different motorcycles throughout 20 years. So I say well done anyway.
The bad: Fox dirt paws. Absolutely insulting. I got blisters at three different points on my left hand (clutch finger and two on the palm) and another two on the palm of the right hand. But wait, theres more: They fell apart in about 4 rides. Not worth their weight in dog crap.
I'll surely think of more soon and post it up when I do.
