Ive always believed that the OEM LC fuel cap was alloy. It has the offset lock and all LCs had them...
but.... Ive since found some here were made of plastic and not alloy, and yes still with the offset lock. I believe these are original Yam caps as opening them up and checking the parts they all seem to be Yamaha parts, not aftermarket.
So, Im starting to wonder if the early bikes (80) had the alloy cap and then if the later ones (81/2) came with plastic caps that look outwardly like the early alloy units.
Of course in 83 the YPVS units came out, with a central key position... cap still fit the LC, but wasnt 'really' an LC fuel cap.
So, can anyone confirm this for me?

I must admit, I have never seen or had an alloy fuel cap (and virtually had LC's for 30 years since they came out (with gaps in between) I've got an early ish 250, and a few spare tanks etc, and test each cap to see if I have the 'Holy Grail' Seen a couple on fleabay, but refuse to pay the prices asked. So yes most are/were plastic, and definately offset (as the off set must face the front of the tank )

Alloy caps had an arrow, and plastic didn't. Mine is plastic and offset key and late 1981.

Wow, it looks like ive finally found a question that the brains trust on this forum cant answer haha. So.... Is it fair to say that we think that sometime in 81 the caps changed from alloy to plastic?

The only alloy (arrow and offset key) cap I ever saw came off a 3 stripe RZ3504U0(Jap spec 350LC). All the other 7 LC350/250's owned by a mate and me had plastic offset key caps. Bikes covered W to Y regs. Not sure this helps your theory...?

Cheers Kev. It could well be the case that not all markets got the alloy version. I know for a fact the Aussies did as I have one on an Aussie bike, it could have been got later tho, but im not sure anyone would have known what it was until the mid 2000s, no one cared before that, they were just cheap transport here.

What years Duncan? stripes on spare tank and compliance plate on bike should tell us, but I bet your bike is an 82, complied either moth 3 or 8....
Ok.... I am now starting to wonder if the alloy cap I have is a rogue and came from another source, but I just dont see how or when that happened. it came with a whole bike in parts that had been off the road for years and was an Aussie supplied bike, but... anything is possible of course and people do buy stuff from all over, even back in the day... the plot thickens.
Of course this is helped by the fact we didnt get 80 model LCs here in aus... only 81 and 82s... Maybe Ive proven already that my alloy cap was a later addition to my bike... :/

Wow, that really does sounds like they are as rare as I was worried they were.... and means the fact I have one in Aus is quite special as we didnt get bikes in 80.
Thanks for helping define this stuff guys, its appreciated!

Cheers Duncan for the info, I reckon we've deduced that (Japan market aside) at least for the uk markets that its early bikes for the alloy caps, and that means non tie bar 1980s. Anything after (81-3) was plastic. That also means we should not have any in Aus as we only got 81 onwards bikes... but... we did have more of a tie up with the JDM models back then (we got the 84 RZ250R '51L' models in 85 and no one else did etc) plus we were known as a habitual dumping ground for old models (or parts made from them) from the Japanese catalogue; our 80 XT was a right dogs breakfast of old parts, some not seen since 76 (ie the loom/keyswitch etc). So its conceivable we got some 80 parts on our early 81s, tho we have none of the early non-tiebar models in Aus unless they have been imported since, so the mystery of my alloy cap remains just that... what is strange is that it is keyed to the seat lock of my bike... Ok, not impossible to do after the fact, and I rekey locks often, but few did that stuff back in the day...
