Harvey,
Welcome to the forum. You've got the making of a great project there. If it had been the case that the wear and tear that's showing there was the result of hard riding for the last several years, I'd say, yes, get it running and have some fun riding around while planning the restoration or fix-up. Having set for 30 years is a whole other issue. Right now, things inside the engine may be in fine or decent rebuildable shape, however, if it turns out that there is crud blocking oilways (particularly to the rod journals), you open yourself up to a much more difficult and expensive rebuild. Cutting to the point, based on sitting for 30 years, my advice would be to strip down the engine before you start it. Having said this, I'm well down the ranks from the best mechanics on the forum, so I'd also love to hear what others have to say.
