I bought an Azusa kit from the same people who bring you this website. It was easy to put together, I originally used a "Harbor Fright Preditor" engine, worked great and the price was right, but then swapped it out with an old classic Briggs & Straton 5 HP engine. With the Briggs I used a CVT kit, that worked out great and would fit with the B&S engine. What is only adiquite is the brakes. Get it moving and you'll want a great deal of room to slow it down. I added a second brake to help. I got the Azusa with the large wheel option, the frame comes un-finished, I painted it "Highland Green" a Ford color. Came out great, looks the part. The cost for the kit was very reasonable. With that CVT clutch it will climb walls and will get moving nearly 35 MPH as measured by my GPS. Everyone who sees mine want one and asks about 1,000,000 questions about it, if they have a minibike bend. Mark one gold star up for the Azusa.
