In my early 50s, riding since 1980. I've owned around 25 bikes, mostly Honda singles, 2-stroke triples and Bultacos, plus a BSA B50 and a '79 Bonnie (the first bike I bought new). Worked for a few years behind the parts counter at several Japanese bike dealerships. Did some vintage roadracing on a Bultaco 250 in '95-'86. Have modified bikes in this way and that over the years, but nothing "all the way" until my glacially progressing Bultakenstein project. Gradually acquiring better tools and knowledge. I write regularly for Hooniverse.com
I took 12 years off from bikes to play with PWCs. My wife and I own Can-Am Spyders to tour on.
