My asking price for the Yamaha dirt bike will include a Clymer's Vintage 2 stroke owners repair manual that covers repairs and maintenance procedures for many Yamaha motorcycles.


The used Yamaha dirt bike for sale is a little motorcycle to ride, not a racing bike, not too powerful but lots of fun! 1st and 2 gear will pop the wheel up when you hit the power band and top speed is around 80mph. I think the engine is about 22hp but I'm really not sure.

WORK NEEDED on the 1971 Yamaha CS3

For this old Yamaha Dirt bike to be streetable once again a few things need to be taken care of and you

20% off bags, covers and other motorcycle accessories

should know that nwvintagecycleparts.com has all of the motorcycle parts for sale that you'd need for this bike NOS.

The motorcycle's tires are old and starting to crack. The clutch actuator (worm gear) needs to be replaced and I HAVE THESE NEW PARTS but they need to be pressed together. There is no clutch action until this is fixed. The ignition (key / switch) needs to be replaced or fixed. I opened it up and it is missing a spring inside to make contact as you turn the key.

I added a section of spring from a ball point pen and it sort of works.

The wiring connections needs to be completed to the ignition switch. The motorcycle's seat needs to be recovere reupholstered but the original foam is reusable.

It needs a new chain because the one that's on it has a few kinks and is rusty.

Spare or parts that have not been installed as of yet

    ignition coils

  • relay box - rectifier

  • rear axle w/sprocket

  • front axle

  • Original air filter housing (missing rubber "Y" tube)

  • Oil Pump (I think it works, but it may be too old to trust.)

  • oil pump lines

  • tree / bar clamp (nos with some rust)

  • chain guard

  • foot peg bar (for high mount exhaust system that was on it before)

  • Miscellanous bolts, fasteners, bits and pieces

  • front fender + braket (some rust and it's pitted)

  • headlight

  • brake light bracket (cheap aftermarket 'oem replacement' that doesn't fit well)

  • NEW crank case gasket (never split the case - not installed)

  • Misc extra control cables

  • Other 1971 Yamaha CS3 Details

    I removed the oil pump and it runs pre-mix now. The foam of the motorcycle seat as seen in the picture is in very good condition. The only problem being one bad spot that is visible but the other side of the seat is fine.

    Pay no attention to the way that the bars are mounted in the pics this is just how they were without positioning them.

    It did have high exhaust but that has been swapped with low exhaust (pipes, footpeg cross bar to let low pipes clear. I still have the original striaght foot peg cross bar if you want it.
