Nothing. Have changed tires due to age and cracking, but just routine care is all that has been necessary.
Discovered the hard way that the battery acts as a voltage regulator for the headlight. Original headlights are over 75.00, but knock-offs from Malaysia can be had for under 20.00 delivered.
I looked that the "bike" very indignantly when my father bought it in 1982, but have gained a healthy respect for it since. He put 5,000 miles on it delivering meals-on-wheels to older citizens, and I have put another 5,000 on it since I had to give up larger bikes due to physical disability.
This thing just keeps running and running... starts immediately and is so easy to maintain. The fact that it gets over 100 mpg makes it quite attractive with current gas prices. I've turned down some nice offers to sell the bike -- it has sort of grown on me!
Parts are easy to come by online. I've replaced a muffler and a headlight and two tires in 8 years.
Being 67 years old and finding 1981 C70 with less than 2000 miles on it for $200.00, I feel like a kid in a candy store. Awesome little bike, still learning how it works, all the forum comments have helped greatly, thank you all.

Need some advice on the blinkers on my 82 Passport. What is the check process? The bulbs are good, taillight works, brake light works, (foot applied/hand applied). Headlamp doesn't work. Any suggestions?
