If you have a really fast moped, and are good at riding it, I've got an idea for you. There are velodromes all over the country, with people training all the time.... See if you can motor-pace for them.
It's the steeply-angled bicycle track, like in the Olympics. You get up to speed, and they draft off of you, for training. You have to be able to get going pretty fast, and hold it for a while.
My brother was asking me to do it for him, whenever I visit, but it's a little far to haul the moped (10 hours, and I never leave the state). If anybody is in the Houston/Katy area, I can put you in contact with him.
Mopeds, and small motorcycles are good for this, because of the size, and the ability to keep at a constant speed. The other things they look for is low exhaust, so they don't sit there breathing your fumes while riding.
If there is a track like this around you, see if they will let you "help them out"
