    Just picked up this treat, will have to cut my teeth on beezers, but she starts 1st kick and seems to run reasonable well, first order of business will be to locate a factory manual for the 70, I know the 70 is a bit different than the earlier A65's, but am not sure of differences with later models...

    I remember my 650 well. Hope you can survive the vibrations.

    Strangely enough I find it to be remarkably comfortable to ride, much more so than my T120 or TR7. The P/O had the crank dynamically balanced when fitting hi-comp pistons so that's likely the reason. The other interesting thing I didn't expect was how freely the A65 revs, I'm regularly cruising around town in the 5K + rev range and she doesn't feel like she's going to grenade. Quite unexpected. Anyway, she's due for a top end rebuild at the very least, and I may even go for the devimead mod if I can find a North American outfit that still does it.

    The thing is with classic British big twins is, once you have complete assurance that everything whirling around inside is doing so in the specified manner, you mind your tach and learn to love it all the way up to the red zone. So what if it "sounds" strained, or "feels" busy, it's NORMAL. Enjoy it.

    my 68 A65 had a high frequency vibe that made my hands tingle after 20 miles or so....I went to a nearby gas station and bummed a double handful of lead tire balancing weights which I stuffed in handlebars vibes greatly reduced …...el cheapo style
