one thing no one has mentioned: I dont know if the VS1300 engine has adjustable tappets, or self adjusting lifters. The 1600/1700 engines have lifters, but they have two valves on one lifter, so every 16000 miles those two valves need to be adjusted relative to each other, because the lifter will put one at 0 clearance (whichever is tighter) and the other will have a gap of a few thousandths...
If you have the service records and the owners manual (available free online as a PDF file) look up how often the valve clearance needs to be adjusted (if ever) and if it has been done as required (service records).
Edited to add: having your valve clearance a little bit loose is not a terrible thing, it wont damage the valves until it gets very loose. Having the valve clearance tight will cause valve damage, because the valves will not close all the way, and hot gasses will blow between the valve and head seat, causing damage to both.
So if you can hear your tappets (tappets gonna tap...) its better than if you cant hear them at all - that would be really bad, the indication they were not properly adjusted (maybe adjusted when the engine was not over-night-stone-cold).
