I own a 1974 Honda 350 F that my son purchased in the late 80´s. It became mine in the early 90´s & I rode it to work for several years. I found it to be a delightful little bike. I had to park it because leakage from oil passage O-rings soiled my clothes. It has been sitting for about 15 years. The only mechanical problems it had were the oil leaks & a binding spark advance unit. I hope to resurrect the in a year or two.
