Are you aware that these are dry sump engines?

They tend to run for a very short while when used with no oil tank,
that is of course, unless you have devised another method of containing the engine lubricant.
A heavy jacket with large pockets and a concealed tank perhaps, or an enormous plugged set of
handlebars, they may get a bit warm though.
Really i suppose a 71-72 bike would be the closest you'd get.

As Nick mentioned, you could always put the oil in the frame wink

Hey Walker22,................. Welcome to the Group! You'll get used to the dry humor! I had skipped over this post at first, as the title made me think you were just trying to get the tank out of the frame!
Anyhow: Yes, you have to have a tank somewhere to supply the pump. These motors take oil from the tank, and return the oil back to the tank. No Tank, No Motor! Tanks are not hard to find, I have a few to offer if you need one. Getting them into the Frame can be a challenge, especially with new rubber mounts. They will be too stiff in my opinion. I save squishy old ones when I find decent used! Anyhow, good luck, and come back with some updates! Did you say what year and model you are working on? KC

My assumption was that the tank was "missing" from the "16 boxes of parts" because it's an OIF bike.

That's why I asked for some idea of what the bike actually is.............. Who knows? Maybe Walker will give us some numbers to go on. I see he posted previous, so maybe the bike ID was made then...? Just curious. OH Yeah!! Now I recall, mystery solved:
This fellow likely was ignored at first. It was an Oddly suspicious 1st post. It's a '66 "special", and likely not going back to original configuration, so any Oil Tank will do.
For once!..... Almost the ONLY time, my search attempt did work!

I don't think that's it KC, because I replied to his post on the same day that he posted. He then came back a couple of days later, totally ignoring my post and something about no interest, so he would rebuild it. Finally, after other members alluding to a sketchy first post, he then claimed to be in the middle of moving and didn't have time to check back in.

I have to ask....why post up parts for sale...in the middle of an alleged move, and not check back periodically ? Why not post pics ? And, he claims to be 34, so being a millennial no doubt, he has a smartphone and is probably in it every 2.8 seconds checking twitter, facebook and instagram posts and replies. Which means, he can just as easily check BritBike. But no, he probably has "ADHD" which seems to have afflicted about at a minimum 75% of his generation and if true, he has already forgotten about this site and is back on instagram posting, while eating dinner with his wife and children who also have smartphones with their faces buried in their screens while all seated out to eat or at home at the same table. facepalm

I do recall that 1st post. And I do recall being a bit on guard, and watching for the response to your careful reply. Vacuum. I dunno, let it lay I guess.

I agree with some of your comments John, like why post if your in the middle of a house move, unless you can keep up with a post it seems almost pointless. I understand the lack of pics though. I’ve just moved house and trying to get photos of anything is almost impossible, still trying to sort out the new workshop is time consuming also.

Being 34 myself though we’re about 10 years out from being a millennial. Can remember a time that the only mobile phone was a car phone and that was only in the cars of people who were very rich. ADHD wasn’t known or when I was a child and only something I’ve see come about in the last 15 years.

I guess not everyone is at their keyboards several times a day like I am. I inquired to the OP about his BSA parts and he did finally respond. I bought some pushrods.

I am looking for an oil tank hacksaw. A65HA141 42-Y is the engine code and A50C.552 is stamped on frame. Im still unsure which oil tank will be needed.

Thanks for the love from most, but damn John. Way to just assume. No wife No kids only on social media when im pooping. Also have a full time job plus second job working on cars, mostly hot rods. I can take heat for being a newbie and for asking dumb questions but when u come at someone without knowing anything about them and throwing them in a class,group,generation etc. It just aint right.

Looks to be a '66 or '67 Hornet (?)

I may be wrong but I would think just about any A65 oil tank would work. I needed one for mine and found on eBay.
You have to take off the rear tire to install/remove. I tried but could not force it in any other way. smile
Thought for a moment you were looking for an "oil tank hacksaw", which is another way to install/remove.

Thats what i had it pegged down to. Ive been bagging and tagging parts for a few days now. This would have been much easier if the previous owner would have done a better job in doing so when he disassembled. The crank,bush and cases are currently at a machine shop getting reamed and balanced. Ive just placed a couple of pricey orders for misc. parts i was missing. Im also still working on retrofitting a modern front triple to the bsa frame. Engine assembly will start as soon as get the parts back from machine shop.

Ive got an oil tank hacksaw if you need one smile

In my book there is no such thing as a dumb question, you often get dumb answers but no question is dumb, some of the time you want to make sure of something before you do something that later proves dumb.

I find a lot that you’ll speak to someone who (after only just meeting you) try’s talking to you like you don’t know what a nut and bolt is, later to find that they have never worked on a bike themselves.

Nice work with the other previous projects by the way. Also Thankyou for your sponsorship to the forum.

Thanks Allan and 25 bucks for the best information available seems cheap! To stay on topic with oil tanks questions Im wondering how hard it would be to reverse engineer the original oil tank. Im fairly good at fabrication and am pretty sure the big bubbly original oil tank isnt going to mesh well with my build. I currently dont have one but i may try to source the cheapest one i can find and cut it up to see inside. Also i see lowbrow customs sells a few but looks like they would need some modification anyways.

Hornets used a least 2 different oil tanks .
The frame mounts should provide the clues to which one was fitted .

It does not sound as though you are doing a stock rebuild
But for reference :

If you would have been more diligent in your replies and acknowledgements, I wouldn't have come at you...you brought that on yourself. You f'n work long hours and I work f'n long hours, no one cares. What they do care about, is knowing if you are legit or not. Don't be a newb to a site and come on like you did. As you can see, it wasn't the best newb intro and you caught s't for it. Big f'n deal...and f'n own it.

I'll be more than happy to accept you, as if you'll note, that I was the first to welcome you to this site. However, being a seriously long time member of this site and seeing so many come and go, as well as being familiar with the patterns of more than a few passers through, it is what it is in my initial assessment of you. Maybe we'll become BritBike buddies....maybe we won't. If we do, great. If we don't, it is what it is. Lastly, you are a millennial, that much is true wink

I will say, that I am impressed that you came back. And, on that note, I do have a stock type rear frame section that I might part with.

Cheers man beerchug
