what was the advantage of this over a YZ 490? it looks like you chopped the back end off the left motor and ran it all through the right gearbox. how did the gearbox like double the power going through it?

Thanks Walter,
Looks like the pistons rose and fell in unison or was it 180deg firing???

Did Eskil Suter do the work on the crank?

Eskil only lives a few Km away , but I used a toolmaking company to make a new pin to make it 180 degrees. If they where 12 grooves it would not have been a problem . But no ,Yamaha hade to make it 13 ..... So one half of the connector has to be staggered to make it right. As ignation we fitted a Kroeber .
