I have recently restored another '74 RD350. It's pretty much stock. The engine is fresh with factory spec compression. I had to clean the front forks and replace the seals. Rebuilt the front brake caliper with new seals and pads. Other than that, it was pretty much cosmetics.
I had never ridden a stock machine so I had no reference to compare my modified bikes to. I was surprised how good the stock bike is. Even without mods, those things turn on pretty good. I noticed that a stock machine gets on the pipe at around 5000 rpm and accelerates impressively. It still needs some good rubber so I didn't take it past 70 mph.
I know on my modified 350 and 400, if you wind them out through the gears, they will accelerate with a sense of urgency. If you whack it wide open in first and second gears, the front wheel is off the ground. To make good quarter mile times, you have to keep your weight well forward through first and second gears.
What's amazing about these old things is how well the engines take abuse. I have my modified machine's ignition systems set to cut the revs at 10000. In race form, guys run their 350s up to 11300 rpm. Considering how old these engines are, that very impressive.
These are pieces of history that just won't die.
