Oil in frame

Just realised I still had this in my phone from the one I did a month ago.

It was posted 2-22-24 it Facebook "classic motorcycle racing" search under "newest activity" The link doesn't work when I paste it here.
I joined the group, and scrolled down in "recent media" to Feb 22, 2024, and looked at all the photos that day. I didn't find this one. Any other suggestions on how to find it?

Sorry Ken I made a typo. It was 8-22-24 not 2-22-24 posted by Trevor Fleming in Facebook "classic motorcycle racing" choose newest activity and page down. I can't get the copied link to work on this forum but I'll email it to you.

AMC's Pluto frame preceeded BSA/Triumph's P38 frame by more than a decade. Constructed by the Experimental Shop and drafted by the Design Office early 1960, two frames appear to have been made. Rigorously tested offroad, all infant deseases had been ironed out. Yet it was not put into production. Maybe AMC feared the buying public's verdict? The frame depicted is the genuine article. According to reports, it rides very sure-footed.

IMO, an OIF design like the one depicted in #1 needs a robust casting at the lower end of the spine tube.

Thanks for posting that. It's the first decent picture I've seen of the Pluto bike. Do you have any more?
 
I do have some pictures of the mods but can't retrieve them just yet. They are in my old lap top which has crashed, something called the Blue wall of death I believe. I'll be taking it to a mate of mine in a few weeks to see if he can rescue my files, as I haven't got a clue how to.
Failing that I'll be doing another frame for a T160 in the very near future, so will post piccies then.
Also, I do brace the swing arm pivot tube with a 3mm x 20mm strap which I bronze weld around the main tube & back to the s/a tube.
what model lap? if the hard drive is easy (often a few screws) to pull? you then just need this cable to plug into usb, on a working pc

take great care in handling a spinning mechanical drive, they are easily damaged

some here 5-6 bux



another more complicated way is burning an iso to cd or usb drive, then bootin from it,

Thanks for your help, but you may as well be talking in Swahili. I literally don't have a clue with compoooters hence giving it to a mate to sort out.
 
There are advantages to oif
The main one IMO is the whole frame acts as an oil cooler
It takes up less space
You don't have the additional weight of an oil tank
The only disadvantage I can think of is they are difficult to clean out
Second disadvantage....it is possible to burn your legs on the frame in longer races.....ask me how I know!

Yes, they are difficult to clean.

('Cured' with more seat padding, to raise the inner thighs away, also helps with leg room, but makes neck angle more acute, which affects helmet choice!)

Needs some mods when it next gets built. I want to fit a reed valve lol. I had lots of leaks, filler cap at the top & drain bolt at the bottom. Was oily around the swinging arm spindle area but was never sure if that was the frame. 3 1/2 ltrs! Not my idea of safe but such short classic races now.View attachment 116015
I would not like to race this. It is short stroke and has separate pipes. You would always need to be 100% on top of it. Also, being unit construction, it probably has a wide ratio gear box. My first race bike was similar. I was always in terror of being balked in corners. If it fell out of the power band in a corner, the clutch had to be slipped and the bike would immediately go sideways. Some people believe they can build a bike which is better than a Manx Norton - the Hannah Paton was around in the 1950s. It is now almost as good as an MV3, but you would probably need to be a hero to ride it. There was a race at Spa during the 1960s where Percy Tait won a race and beat Ago on an MV4 with a 500cc Triumph factory twin. It would have had a lot of parts which the ordinary punter could not buy. And Percy was a bit different from most of us.

If you buy another computer, sometimes the hard drive from your old computer can be plugged in and accessed. My computer crashed a while back, so a rellie bought the bits off the web and built a new one. I had it running with two hard drives and was able to transfer files. However Windows decided there was a conflict and turned nasty. By that time I had saved most of my stuff. It is the automatic updates which seem to cause a problem - my old hard drive had an earlier version of Windows on it.
I do not usually stuff around with hardware, I just use the computer as a tool. I am not familiar with the current architecture. The ones I grew up with had complete wired through boards which were plugged in to fix faults. If one board stopped working, nothing else worked.

We covered Percy & the factory Daytona special engine Al & Percy came second to Ago.
My bike has a 5 speed Quaife easy to ride, ride fast? Led a race at Lydden for 4 laps before Tim Jackson got by. I think with a few changes it might be mid pack competitive.

Agreed, you can’t fill that OIF to the brim !

The effect of hard braking will also be a consideration.

The ideal fill height could only be arrived at via trial and error I guess.
On your last point, yes. I have used different levels in my Rickman over the years. Too much oil and there is excessive breathing from the forward breather pipes and seems to run hotter than the right level, my guess is this is due to inhibited flow. Too little oil, and it also runs hotter but breathes less, or even nothing.

Rickman say 6 pints for pretty much all of their frames, and when there is a sighting pipe this is consistent with the indication after the first running on fresh oil.

Lo and behold, 3.5 litres (6.15 Imp Pints) seems to work well in mine and is my choice for longer (20 minute) French or Belgian races!

For shorter (10 minute or less) UK races 3 litres (5.3 Imp Pints) seemed fine.

I'm reluctant to put less than 3 litres in, but that is just a bit more than Commando oil tank capacity anyway!

A fabricated oil tank for a Seeley (or modified Rickman) is likely to be around 5 litres capacity, but in use the oil content should be no more than 3.5 litres to allow 'breathing' space!
