I need a motocross/dirtbike riding class to take?

I live in central Illinois and would like to learn how to motocross race. I trail ride quite often with my buddy, but it's not quite as fun as what jumping and racing appear to be. I'm 16 years old and usually ride a 1994 honda cr250 (2stroke). I also have a 2003 Suzuki drz 250 (4stroke), and another Suzuki 125 (2stroke). My main concern is getting to a class that will teach me how to jump and race while doing so safely. The one time that I tried to do a jump myself with no experience, i dumped the bike and bent the subframe beyond repair. I would like to join a sort of beginner's class that will teach me how to jump and maybe how to race.

Side note: I would like to keep the class relatively close to where I live, so please post the location of the class.

Where can I buy affordable cr125 engine?

I'm about to build a go kart but I really emphasize on the engine I'm about to pick. Reason being, it's the heart and soul of a go kart and the Honda CR125 engine can basically go on every surface (rock, dirt, mud and even race tracks). Nevertheless, I found some results but then engine only has the bottom end, or is still attached to the bike (which makes it really expensive!) and it's hard for me to find results since I live in Canada, Quebec. Where can I find affordable cr125 engine (or you can even give some other good engines that can withstand what the cr125 can achieve. Ebay and Kijiji are difficult sources for me because most of the buys are from other countries (especially USA). Where can I buy them (for about 500$ ish) or you may suggest some other engines I can put on my go kart (dirt bike engines) that is as affordable.

What should I expect riding highway 50 from I-15 in UT to Carson City, NV?

My girlfriend and I are riding my Honda Interstate from Salt Lake City, Utah to Monterey, California and back at the end of this month. We're planning on using Highway 50 on the way out there then traveling north to Sonoma County, California. We will be returning along a different route TBD. We'll be taking two days for the long legs of the trip with Carson city being our stopping point on the ride out. What advice or tips can anyone provide about Highway 50?

I've prepared the bike with a new seat, high back rest for my girlfriend, luggage rack, windshield, full face helmets with Uclear intercoms, and saddle bags.
