These links might be of interest. I couldn't see any YDS3 manual, but it might be lumped up in an all round Yamaha 2T Twins manual.

Oh chur, That is helpful.

As husaberg said, Crank clutch and iron barrels.
That could be a rare one by the sound of Glass tank and old Amal carbs ??? If it's genuine ? Might be YDS1 !!!!!293496

Yup, ...pull in clutch while running, disengages revcounter and oil pump. Former not so bad,...starting revving though and bye byes.. I would love a YDS3 though. My old man had one back in the '60s

Hey - i do have a couple snaps - you will have to check them out on photobucket. my computer was having a hard time trying to get them uploaded.

Dont laugh , I havent "started" on it yet, but you can see its going to take abit of work,

i wont be throwing alot of money around because it doesnt have plates or papers and would probably never be road worthy.

frame has been cut and relded in number of places but is deffinately straight.

That looks a bit of a challenge for you.
The Amal type carbs throw me, for that reason alone I'm not thinking YDS2 or 3. My first 3 was a 1964 and the 2s were a year before that. (pre autolube and Pod air filters.)
Maybe you could search engine and chassis numbers to confirm or deny. There would be very few YDS1s in the world I would think.
Good luck.

I found the Yamaha twins book.
Send me the engine and frame numbers and i will have a look.
I will also post the relevant sections.
to me the Forks seem to definitely be road bike due to the taper.
The frame (due to the rear foot pegs) seems to be a road bike with the bracing tubes added.
the front brake is on the wrong side for a road bike though same side as a genuine racer.
The carbs look are they real amal? which would have been a common mod as the parts jets etc would have been easier to get.
This is not suggesting it isn't something special it may have a genuine race kit or just may have been altered during its life.
Me i am so loving its genuine period looks. esp the bacon slicers and the flanged rims......

Twotempi has the other yam twins book i think which will have more photos and text as the one i have is the road and race version.

I'd call it a homebuilt TD1. Whether it's from a DS2 or 3 i don't know.

You'll find out how serious a racer it was when you lift a head. If there's hand cut extra transfers - Z shaped slots - it's TD1C copy.
A lot of these and Suzuki T20's were built up in period and made quite good racers too.

personally, I'd abandon any thought of turning it back into a road bike - too much unobtainable stuff is missing, I'd rebuild it as a period racebike and look for the occasional parade event to run it. No point in trying to race it seriously either sorry....

Very interesting to see a survivor from the early 250 wars though.

Carbs look like Amal TT. Float looks like Amal GP "matchbox", and I reckon the front brake is Yamaha XS-1 (650 parallel twin). XS-1 had removable plugs in vent holes in the drum

Carbs don't look tt to me...... they could be the mikuni copy of the 275 or be just 275 amals. what are they numbered? The float is def Amal of course

Hi. From the pic's I would say it is based on the YDS3. The left hand side of the motor shows a cavity where the autolube system sat under a cover. Autolube was introduced with the YDS# from eng No d9-9704. Definately a YDS3 modified frame and the forks are road based as well. Love the "Bacon slicer on the XS-1 front brake!!! My books say that a MIKUNI 276 carburettor used in conjunction with a TD1B cyl was the standard mod for racing back then. Good luck with this some engine parts are still available on E.Bay. I am at present restoring a 1966 YDS3 that I have owned since 1978 and it has sat in the shed a good time of this. If anyone knows of a seat base or right hand muffler give us yell ..

Like an big jdiot I turned down a 1964 YDS3 about 10 years ago.
It was even restored !!! priced at only 2 grand !!!!!! A mate didn't want to take it to Auckland with him.:facepalm:
I'm in a very different position now and would grab it with both hands.There is a lesson for us all in that one.
