I posted this in C&V since it is a C&V tandem, but could use ya'lls help on clarifying something.

Check the right rear dropout for serial #.
The eartly Burleys are still nice and $175 for that bike is a super price! That bike sold for a minimum of $1,200 when new.
Did some test riding on one of the first Burleys back in 1988 for an article we wrote.
Enjoy the ride TWOgether!

Can't help on the serial # location but NICE BUY! Keep it tuned and that thing will give you a heck of a return for a $175 investment -wow!..........want to manage my 401k?

There are many techniques to try, just start with the least aggressive ones (Kroil, PB Blaslter, etc.) first and work your way up.
Regarding the cranks almost 180 degrees out of synch -- spend some time searching in this section for "out of phase" or OOP and maybe even give it a try

Alright I posted more infor and pics in the original Thread, but I'm gonna ask the main question again here.
I looked for the serial as Zonatandem suggested and founr 5207. I don't know if that mean the 85 or 95 or the 207th frame of the year, or the 07th frame in February, or something completely different.
Any help would be appreciated.

Out of Phase (OOP) by 180 degrees will cause excessive frame flexing, and should be corrected immediately. I suggest Captain's pedals be 90 degrees advance of Stoker's pedals. That way, there are no power surges, and someone is always in 'power position'.
(We're 15 years in 90 degrees OOP.)

While I cannot totally demistify Burleys serial numbers, seems frame was built in "0", 1990 sometime.
Handled tandems for years and checking some of my old records, 1990 is likely year of manufacture.
Agree with Front Half in Canada to put pedals 90 degrees OOP. This will minimize frame flex/tailwag efffect of pedaling in phase or 180 degrees out-of-phase. Also less wear and tare on drivetrain components + smoother/easier climbing.
Been pedaling OOP for over 225,000 miles. Yeah, we prefer it.
Pedal on TWOgether!

I bought a new Burley Duet in 1989. Its serial number was 1560 iirc.
My 1989 model had 6 speed with 27 inch wheels.
They went to 700c wheels shortly after 1989.

I'm not sure that bike is quite that old. Frame looks pretty similar to our Burley Duet, which we bought in 1994. (however I believe it was a 1993 model.)

Also ours came with originally with that Suntour derailleur, and a six speed freewheel.
My understanding is that Burley changed the design of their frames at some point to go with the design of your bike where the top tube is one continuous tube with openings where the seat tubes pass trhrough. Someone more familiar with Burleys may be able to date your bike based on when Burley changed their frame design.
As for the seat post, take the eccentric out (The piece the captain's crankset goes in) turn the frame over, pour penetrating oil, or a prodct like PB blaster down the seat tube, wait a day, then try to twist the seatpost out.
If that fails, cut the seatpost off and drill out/cut out the remainder. A dremel tool should work if you have one.
