Back in 1967 I had just finished rebuilding my 1965 Honda 305 Superhawk:

I had it bored-out to 339cc's, ported and polished the intake/exhaust ports, installed a highlift cam and a new aluminum composite clutch. It looked showroom stock (except for the candy-apple blue paint job and the extra chrome), but this was the bike I got up to around 115 mph
Years later (I sold the bike above when I got married) I bought a 'basket case' just to have something to tinker with. It was a 1967 stock 305 which had been left in some guys garage for about 10 years after his son went into the Army and never was interested in riding it when he got out. I only paid like $150 for it as it didn't run, but it was in good shape, the only thing that wasn't stock was the megaphone exhaust pipes. I tore it down to it's gaskets and repainted the frame, this time candy-apple gold, and reduced the weight and made it into what looked like a 'cafe racer':

But it looked much better than it ever ran. I think sitting for 10 years without being even turned over took it's toll on the bearings and the rod bushings. I left the engine stock except for the intake velocity stacks and of course the exhaust. I drove it to work for about a year but then it started to act up and I unloaded it. I always wish that I could have had that punched-out engine from the '65 in that '67 cut down frame. Now that would have been something.
Anyway, that was the last bike I owned. I've always told the wife that when we retire, it's going to be either a Winnebago or two Harley's
