Ken,
It would be great if you/we could organize a shop day. Pick a topic, for example how to adjust the valves. Have 3 to 4 guys that know how to accomplish the task. Have them supervise all of the guys working on their bikes. You can stock up on shim kits or other products that are needed for the days work. We can buy the necessary parts from you.
Fire up the BBQ and sell drinks. The profit from the food will create income to support future shop days.
Another plus is that we will all get to know you. The more personal the experience, the better chance that guys will continue to buy supplies from you.

While I'm at it, I have another suggestion. Sell sings that say CRF's Only.com with a moveable arrow on it. Just like the inexpensive sings that a realtor uses to point out an open house. http://www.signoutfitters.com/store/lis ... tegory=242 Next time I'm in the desert I can use the sings to mark how to get to my camp. You could also offer a BIG CRF's Only flag that could hang from the back of a toy hauler.
Just some ideas,
Rich
