Sellers like him help to wake up old bikes from the dead.
Fresh bikes and parts from the bike grave yards back to life!
Also make a better market for all these old bikes when there are service parts available. Maybe even easier than to much newer bikes.
Just ride your old bikes, spares and service parts a few days/week in shipping away

I have seen some small NOS CB750 parts enter crazy price levels on eBay.
Especially German sellers. Ignition cover, the small outer clutch cover. Caliper holder etc.
