I'm not sure what the criteria was for not being given a Q plate on an import back then. In the early eighties, I bought a  US import RD350 (A, I think) from Romsey Motorcycles that got a plate dated from when it was imported/registered - APR136Y, and I'm pretty sure it's still at the back of someone's shed.

I owned this bike as well for a couple of years around 1990 ish. I bough it privately from Oxfordshire I think and sold it to someone in Brimpton, Berkshire. The story I got was that it was imported from Germany by a US serviceman. It was a 1974 A model and had the round back light. I've got some photo's somewhere. Whilst I owned it the crank weights came out on the M3 and made right mess. Crank was repaired by SEP and I had it re-bored locally by a chap who supplied pattern LC pistons. It went ok but always rattled after that. looks like it was last taxed in 1999, but had a new logbook issued in 2002.

I'd love to see some photos of it, if you're able to scan and post them.

When I first bought it, it would never rev out. I knew even less about carbs then than I do now  :o :D, but I bought some replacements from a breaker in Bath, fitted them and it went really well after that.

I've been looking for the prints but think they are buried in the loft. It's a bit cold to go up there at present, but I haven't forgotten and will find them.

There was a batch I know of 6 or 7 RD400F's registered by Padgetts in late 1983 early 1984 on A plates after they did a proper stock take in one of their vast crate storage buildings and found them amongst other old stock bikes !! I know as I worked at the time as a mechanic in a motorcycle salvage and sales shop and we used to supply Clive with new engines for their race bikes from the new crated bikes purchased from them we dismantled for parts we sold which were 350ypvs, 500ypvs, and RG500 yes we broke new ones including a black/red 500ypvs!!! as so many were being crashed new parts were in short supply. I tried to buy one of the 400's when I found out but all had gone. It does happen more often than you think with big storage as again when I worked at Carnells in Milton Keynes they purchased from Yamaha in 2000 all still crated 9x 1990 OWO1's and 17x 1994 FZR400SP's .The OWO1 was selling at £13000 and they only paid £3250 for them........

When I worked at the salvage and sales shop we also had a load of ex Chas Mortimer racing school RD400's we broke for parts and in 1985 we had 8 of the original 1983 31K RD350ypvs which were ex pro-am series race bikes direct from Yamaha all refurbished by them we sold as new bikes on B plates and came with a years Yamaha warranty!! Also a little trivia relating to those ex pro-am series bikes is that they handled better than the standard tank slapper early 31k models due to they all had the headstock angle adjusted before racing to solve slapping by another Man I worked for who Motolined jig frames straight after accidents and was asked by Yamaha to do them as they were uncrated before being prepped for the series.
