The Yamaha 250 Ascot Scrambler was introduced in 1963 using a YDS-2 Frame

Wheels + Forks, (see the Cycle World article listed below).What you see in the

photos is what I have.The bike was parked in 1980 with a full tank of oil/gas

which turned to sludge and prevented rust except for the top front pictured-

a shame because the 'patina" of the "Yin-Yang" tank is so good-badges pads 

and petcock are excellent. The motor has water damage - the right cylinder-was seized

there is a vertical crack in the case by the crank oil hole that needs repair (photo #8).

Left cylinder is good-turns over-shifts through the gears.At this stage of the game though

it needs to come apart for inspection of the right crankshaft,seals etc.To make a true Ascot

motor (as mentioned in the article) you would need to source the top end,carbs and chambers.

To reiterate-this is a 1963 YDS-2 with matching #'s and a clear Title.I can ship it

in the CONUS in 3 boxes for $400.It will take @10 days to pack and ship.
