As Nils said, at your earliest convenience, make sure you have a 469A advancer and not the original 469 one that was installed on all Japanese bikes. Many were retrofitted per an order from Honda, but many slipped through the cracks and were not.

Battery and tires are absolutely needed, but not really the first things needing addressed. The forks/steering bearings need done while you have the front wheel off. But mainly address the carbs/engine. Get the carbs off, check the valve clearances, cam chain adjustment, timing, and yes, the advancer. Do not be tempted to turn gas into these carb and 'see if it will run'. Get the oil and filter out and for sure drop the sump cover and see what's in there. Use a Honda filter only and Honda GN-4 oil 10-40 is great. Stay away from synthetic.

The alternator and all wiring connections need serviced as well. You will find yourself needing various rubber parts, gaskets, seals, service items as you go along. Ask us here where to get those. You will need a couple of special tools - they are available fairly cheaply.


If your gauges prove wonky, they likely will, we have a guy for that too. New gauge cushions at least are a must.

Lots and lots more to do, do a search here and you'll find just about everything you need to know.
