I had an engineering works make up four 6mm mild steel plates - two are 40*15cms and the smaller ones are 10*15cms. They clamp around the lifting bar with 8M bolts as per the photo
The front set are inverted and a scissor jack under the engine tensions two straps around the downpipes
The rear lifting plate is bevelled in one corner to clear the lift's legs, but the amount would depend on the geometry of the bike
There is some inherent flexibility in the Eazyrider but two or three strategic supporting props (I use bits of broom handle) wedged underneath make the whole thing very stable
