I am a poor example of chain mait. but a good example of todays chains, I have over 15,000 miles on my bike and have lubed the chain 3 times and never clean it. Both chain and
sprockets are still fine. Shaft drive is OK I have one on my old BMW but I can't just swap sprockets to gear it the way I want it the way I can on my Triumphs. I have used chains all my life and swear by them. Even if a chain would happen to break as long as you carry tools it can easily be fixed along the road in a couple min. and you are on your way.
Same deal with carbs. if they fail on the road chances are it's dirt that can be cleaned out and again you are on your way.I have been riding for 30+ years and every bike except 1 has been chain drive and they all had carbs and points except the 2 new Triumphs with electronic ignitions.


I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
