FOR PARTS OR REPAIR. Local pickup only. eBay will help you get this done. The engine was rebuilt. I rode the bike two miles. The engine ran very rough. I stopped the bike and rode it home two miles. It has been parked for six years. I have made no effort to start or fix it. It has been sitting. It did shift just fine and smoothly through all the gears.
Today (5/2026) I started the bike back up. It will idle at 2800-3000 rpms. It still misses badly when I took it out. It does smoke but the rings never seated after rebuild since it only went four miles six years ago.
I am selling this as is for parts or repair. You may well have to pull the engine and go back through it.
At the time of this writing there are no completed listings or present listings on eBay for this bike. This is a very rare bike. Jay Leno bought a low mileage CB350F Four for about $25,000. Once this bike is repaired it should be worth between $15,000 - $20,000. Most of the parts in the bike (inside and outside) have been replaced mostly with OEM new parts where available. This is a very nice bike that I hope someone enjoys as much as I did. I am too old to remove the engine again if that is needed. There is no one who would help me to do so. I hope whom ever buys this gets as much enjoyment out of it as I did.
eBay will arrange for local pickup if you win the bid for this 1973 CB350F Four.
