I just bought one of these all completly stock and with only 13000 miles, a lady owned it and had it always maintained, this bike has always been garaged and now it´s in my kitchen,I have only put 1200 on it. I bought it because it has the similar lower end as my old flat head and I had it for 26 years and always started first kick every time, but this bike is not my primary bike, but sure is fun to ride.... I have heard about changing the tranny sprocket. Have a good day to all...... Gale ......
