My two penneth; the BSA/Triumph OIF Single air filter housing is not what the OP needs if he is considering an 'air box' for Flat Track racing. It is, simply, a unit to hold the simple paper based air filter in the right place. I have friends who race FT here in the UK and they need to construct mul...

I've B44 slipper NOS OEM +0.010" and +0.020" pistons, both have rings but no pin.

PM me if of any interest.

Paul.

beesa71

Whole bike is an M&T replica built solely from photographs in old magazines etc. A real credit to Neil.

Paul.

beesa71

The 'race' B50 is owned by Neil Stuart.

Paul.

Jean-Paul,

A B50 drive will be in the post to you asap.

Regards.

Paul.

beesa71

A gentleman who I was introduced to at Circuit Carole International B50 Meeting in September told me that, becasue of the high prices these drives are commadning on Ebay, he was comissioning a batch in order to offer them cheaper. Does anyone in France know of progress on these items? I think many o...

beesa71

Francois, it will be in the post to you today.

It came from an 'XON' registered B50.

Regards, best wishes and have a great 2019.

Paul.

beesa71

Francois,.........

beesa71

Funily enough Ian, I thought so too. I was sure he looked older than that at the International B50 Meeting in Paris in September but then thought it must have been the womderful weekend and superb hospitaility of our hosts that changed him....... didn't seem to work for me though, still old in all r...

John, If it's Neil S you are referring to the I think he hadn't got the luxury of seeing a bike in the flesh, only a plethora of pictures. Of the bike pictured; in period it was vented to atmosphere via a 'catch tank' (sometimes). M&T didn't do 'valves' then, nor did we! Regards to all OIF'ers. Paul.

beesa71

I believe I am able to supply the pictures Brad needs and have been in touch with him directly.

Paul.

beesa71

Thanks Gerry,

I only have a 'net poor quality scan as yet, I plan to buy the magazine if necessary to do better in terms of the scan.

Regards.

Paul.

beesa71

Just that really.

We have an article in the 1974 magazine that describes an outing by an M&T machine and we can't understand it (reasonably).

Please can anyone help translating the few sections of text that mention the entry?

Regards to all OIF'ers.

Paul.

beesa71

I think we ougth to put this thread out of its misery and simply say that it's a Bandit/Fury frame, or at least its origins are/were. Now modified to suit present purpose.

Paul.

beesa71

Of the many dozens of NOS Fury/Bandit frames we've seen over the years, none had frame numbers. Chell's in Stafford for instance, had tons of the stuff after the factory closed. We bought all sorts of OIF stuff but weren't interested in the 350 items. Anyone evidence to the contrary on any significa...

beesa71

and, Beat, I too am glad to hear that you are back home but sad to hear of the trouble en-route.

I enjoyed to company of my friends both new and old Circuit Carole. A great weekend.

Best wishes.

Paul.

beesa71

Oh no....... I'm more excited now.

I'm positioned 25 miles from ferry as I type this, 00:30 crossing in the morning and will be at the circuit as and when we can get there.

See you there folks.

Paul.

beesa71

Indeed Rickard, it will ne a great pleasure for me too.

Let us hope for fair weather.

Paul.

beesa71

Me too, me too.....

We (John Summerfield from Norway) and I should arrive Friday morning.

Paul.

beesa71

Jim, In answer to your last question; no they didn't although I have one that was fitted with a Nylon sprocket. An alloy rim, as they used of course, helped a little. I will try and post pics of an installed wheel (if nobody beats me to it) after the forthcoming B50 meeting in France. Regards to all...

beesa71

The stanchions and sprongs were shortened (I have evidence) and the rear shock absorbers were, as you suggest Gerry, 1" shorter units.

Paul.

beesa71

"A dove grey frame should have a frame number lower than 101 and would be quite rare and perhaps valuable bike. Numbers below 101 were reserved for factory use, one of which was pre production prototypes and road test bikes for the media." With respect, that isn't the case. There were/(still) are Do...

beesa71

Just to add a little re' the stainless steel MX rear mudguards if I may; they don't have the 'thickening' washers spot welded on around their mounting holes (as the SS/T ones do). Instead, they have larger holes than on the mild steel SS/T mudguards as into those holes are fitted rubber grommets ie ...

beesa71

Crap picture (taken just now in a rush) but here's our stainless steel nut that is a copy of the OEM nut; the plain portion under the hex is 1 3/16" long.

Paul.

beesa71

Simplistically; the nut sticks up through the top yoke. It's function is to set the bearing clearance and, then, the top yoke clamps around it at some point along its plain portion. The hex portion is not to bear down on the top yoke at all. It's an assumption that the bearing 'outer' abutment rings...

Carb on the BSA factory speedway bike was 1000 Series Amal Concentric Mk1. 2 x remote floats as most speedway bikes of period.

Paul.

beesa71

Francois,

See my 'pm' to you.

You obviously know more about the 2 off 1972 bikes than I do, be interesting to add to my information.

Regards to all.

Paul.

beesa71

John,

Neil (to whom I think you are referring in connection with a recent replica); to the best of my knowledge, and what he told me, was that it was all done from pictures. All credit to him for such a very good effort.

Regards.

Paul.

beesa71

John, Indeed, one (most likely the last built/used by M&T) did end up in your part of the world but circumstances dictate that it stays 'hidden'. Hopefully though not for ever. Of others; Of the 2 1971 bikes; all 3 still exist and whereabouts known. 1 in France and 2 in UK. Of the 2 1972 bikes; 1 kn...

beesa71

Canberra; sorry, I missed your comment when posted but may I ask what you mean by "There are a few replicas but genuine - no."?

Regards to all OIF'ers.

Paul.

beesa71

If that was a question, then the answer is no.

Paul.

beesa71

I second those thanks.

I've found the 'net source of the race picture above.

Paul.

beesa71

I don't recall ever seeing one with centralising rings and I would believe I stripped plenty that have never been apart before I did so.

Paul.

beesa71

I've not been able to track down this image on the 'net, can anyone help please.

beesa71

Not the engine being described. The combned oiling to engine, gearbox and primary drive is a nice touch but relies on it all being contained therein. The bike/engine you see in the images is described by me under the following; of the two bikes built by M&T for 1971 all three exist today!!!!! Yippee...

beesa71

Rescued......

beesa71

Also, M&T 'helpfully' used expoy resin to help fix the cylinders to the modified brake plate, they also filled the counterbore around the cylinder nuts with the same - that can also be seen in the above image.

Paul.

beesa71

No Gerry, just 2LS. Each cylinder has two fixings. Each shoe then, at about mid-point, has an 'anti-knock back' arrangement with a nut on the outside of the brake plate and that might be giving the impression of more pivot points etc. I've removed the pictures I took of the inside of a M&T converted...

beesa71

Carlos,

Which journal are the last two pictures from please?

Paul.

beesa71

Always good to see anything M&T. Thanks for posting it.

An English transalation would be good, see what errors have crept in over time!

Paul.
