If you do a good job during the restoration of an old bike, you can enjoy years of riding when your finally done.
Like my WL bobber, I have ridden that bike for 8-9 years now after completion. I have been as far south as Sancerre - France when at Linkert Attack in 2012, and I have had numerous rides in the mountains in Southern Norway.
Of course oils need to be replaced, breaker points too, and general service needs to be carried out, but other than that; no worries - go riding.
This summer have been crappy for the most, rain and wind from North. Then a good trip on the bike in great weather is even more valuable. Below is some photos from what I find being one of the best trips this summer, not that long a ride, just 250km`s in a day, still just GREAT!
