IF the bike is clean and has the original pipes then its not that bad of a price.
these early CB750s are getting very valuable.
they share alot of parts with the $45K sandcast bikes and also benefit from more HP then the 72-76 bikes do to the better cam and free flowing exhaust, the 77-78K bikes are choked and heavy.
the top clamp alone sells for $200 on eBay from the early bikes, forks are different, seat mounts, gauges really they are different animals.
they did make 77K 1971 cb750s though...
alot of the time though most of the "different" parts are removed and lost over time, some times its the owner trying to "update" the bike and others times it people hacking into bikes with out thinking about what they have.
$800 is a decent "retail" price, thing is that most of us only want the "wholesale" price....we are cheap...lol
that being said i bought my K1 CB750 for $300, it ran and had a title, but lets face it deals like that dont come around every day
Thing is that people in any realm of vintage bikes needs to understand valuse, they are not all $100 POS old bikes that we shouldnt care about. early CBs are and icon of a start of an age, kind of like early muscle cars.
Resto and collector guys are starting to pay huge bucks for original bikes, no that causes alot of people to get mad, but why? doesnt it legitimize our hobby?
I personally hate when i see someone take a clean original bike that they bought cheap and cut it up for no good reason, why not clean it up and ride it stock....alot of these bikes work as bikes much better stock then when some are done "making them their own", or at the very least fix it up and sell it for a profit to fund a different project..
anyway im way off topic now...sorry
to know for sure we would need to see pics
