Note the engine builder, if all pics don't show try another browser (not all do in Edge) doesn't say what it sold for. --- https://www.mecum.com/lots/LV0120-403384/1976-yamaha-rd400/

Sold for $5K + $500 fees
That engine was a 75HP package!
He sold it as he was scared of it... they didn't quite get the chassis to work well with that power level.
I believe the frame was stripped and de-tabbed but not much frame reinforcements.
Should post some pics of the inside?

Hell yea!!
Got any videos of it running ?
