Since I was old enough to walk I was out in the shop working on motorcycles with my Dad. He loved motorcycles in general, but was really in to dirt bikes and hillclimbing.

I spent hours in the shop with him helping him make motorcycles go faster. He would often port and polish, fabricate tuned pipes and shave weight. He was known for creating winning bikes for himself and his friends. Needless to say, he instilled a livelong love for dirt bikes in me.

I have contacted a lot of good guys out there and got permission to link their knowledge articles on datafan.com. These are some of the best hard core tuning articles ever written. I am also a distributor for lectron carburetors and I am working on some other nitch performance products as well.
