Starting V Twin Diesel Engine

Motorenwerk Cunewalde 2VD 8/8 - 2SVL which roughly translates into.... Its German which makes it very difficult for me to find info etc. It was made in 1974 It is a V Twin It is air cooled 800cc 3000rpm Rated at 11.1kw or 15PS It has a 80 by 80 mm bore stroke ratio which will probably mean more to some of you lot than to me. It has a dynamo / alternator of unknown voltage and power, I'm guessing 12V and enough. It has had two (second stage?) modification, 2SVL *what ever that is. It has a fan forced air cooling and ducting It appears to have ally heads and crank housings with cast iron cylinders. It weighs 124kg but unknown if this includes auxiliaries like alternator, fan, fuel tank etc I bought it intending to make a 800cc V twin diesel motorbike but time and motivation will be the two limiting factors on this project.
