i bought a 1970 yamaha cs3 pretty much identical to this at auction i feel very fortunate to be the custodian of it. one thing that is different is the things covering the exhaust pipes are black on mine which i believe is factory according to the pics on the owners manual i own
the C suffix relates to the high pipes/street-scrambler features. The were 3 models: UK/Europe/down-under got the CS3E (electric start) and those had shrouded suspension (front & rear) and mid-height handlebars. USA got the CS3B & CS3C. They still had electric start but couldn't realistically be called CS3EB and CS3EC. The B had rubber-gaiters on the front forks and exposed springs on the rear shocks plus apehanger bars. The C had same stuff as the B plus engine skid-plate, high pipes, braced handlebars and a different front fender. The E was (usually) Blue. B was Purple. C was Green
I was going to say that i have a yds6c 250 c is deffiantely means scrambler or high pipes dad had a cs3 as well needed crank seals but werent available in the early 90s hopefully not anymore tho
@@pattoallen1981 I think you can get more parts now for these bikes than when I first got interested in the in the 80s. The internet was a game-changer but I think also knowledge about the seals. Everyone now knows that when there are big running-problems on these 2-strokes first thing to rule-out are crank seals. I did a leak-test on my CS3E engine which hasn't run since the 80s and only leak I could find was at one of the carb-inlets. Some say it's easier just to change the seals rather than do the test but on the CS3 (plus YCS1. CS5 and RD200) it can be very difficult to get the armature off the crank to do this
My CS3C was bought in Norfolk Va. in 1970 (Well's Motorcycles) and the serial # was very low. I think 461 with some leading zeros. The C in the model designated the high pipe street scrambler style. I'm pretty sure it was the only year the 200cc model was built with the high pipes although the earlier model 180cc, 1969, was available with them. The low pipe models that followed had a B replacing the C in the model number. I really liked the green paint but not so much the plum that followed in the low pipe, 1971, models. I don't remember mine coming with turn signals in Virginia. Maybe that was a state-to-state requirement? I think it would top out at about 80mph on a good day. 2 years of HS and 1 year in college before selling for about $250 with 7500 miles. I think it was a little under $700 new. The buyer said he was going to rebuild the engine because it smoked. I tried to explain the 2 stroke thing to him but he didn't seem to listen. Anyway, it didn't need a rebuild.

Nice when it’s all stock and original.
Thats what it’s all about.
Yamaha marketed the bike as a street scrambler. Big bro had one back in the day

Check the Autolube tank to make sure you have 2-stroke oil in the tank. Do NOT foul those spark plugs.
Hope you managed to find a kick start. Bike look nude without one.
Use to own.a 1972 CS Yammy 200cc.
Would love to have that one.

Great story! Thanks for watching.
The carbs should be the first thing to pull and check for plugged jets. They could ruin an engine in no time.
Man oh man did your friend buy a bike museum?🤔👍👍👍
strange that it's done less then 1000 miles and someone has been in messing around with (cutting/crimping) the battery wiring
Agreed, maybe odometer no working?
Nice. Real nice.
will it run? its fkn brand new lol
Good point.
