Thanks Sid,
I have tentatively suggested this bike to Kevin, but with reservations as I was an under bidder for the pile of bits which supplied the engine for it. My major reservations come from the gilded description which suggests that, apart from the UFM, these parts all started from the factory together. The description of an "ex works Upper Frame Member of the same year" suggests that it was supplied for this bike many decades ago. This was not stored as a motorcycle, but as some salvaged motorcycle parts from a crashed machine. It may have been built with original parts but they were from other motorcycles, or second hand bits as we call them.
Having groped through the pile of bits I know that a huge amount had to be sourced elsewhere. Had someone built this bike for himself and then used it, I'd have no problem with seeing it as a suitable bike for a rider to buy. Built for sale and road tested for 500 miles doesn't quite earn the description given.
It may be an excellent bike but as the description is disingenuous it raises my suspicions.
It is conveniently close so Kevin is trying to arrange to see it, perhaps test ride it but for the price I suspect the ex-Ron Vane Rap would be a better bet.
