Be careful, taking a "hobby" and turning it into a lively hood can really kill the hobby. If you get what i mean. I'll explain. When i turned 16 i brought my first bike (50cc moped) followed a year later by a Honda 250. I spent every moment i could riding around, and i had the same idea you have. How can i turn this love into a money making venture. Soon after i started work as a dispatch rider, and did that on and off for the next 10 years. Let me tell you guys. When your riding out in the country with the tempature around 75/80 no traffic in sight and your being paid to ride. Well it dont get much better than that. BUT, there is a down side. Like when its minus 5 degrees, the wind is howling and its absolutely pi1ssing down with rain for the 10th day in a row and you have a three hundred mile round trip to make because the electricity bill is late. Then all of a sudden you start looking longingly at the cab driver in his warm car with the stereo playing thinking, how hard can it be to be a cab driver.
For the most part i really enjoyed being a dispatch rider, but the winter was sheer he11. I swore when i left the UK to come to the US, from that day forward i would never ride for a living again. It takes away so much of the joy of riding.
Now, if i had the money, (and both the managerial and mechanical know how) i would love to have a Motorcycle Retail and Restoration shop. Restore old bikes, ride them for a while and then sell them. That would be great.
Also, one other thing. I am a MSF riding instructor and it actually pays very well.
