Air filter for Slimline singles

Posted by michael_sullivan at December 16. 2017

It has been awhile since I posted the question, but here goes again

Does anyone have a factory supplied air filter for a Slimline Single?

The parts list that I have (Spares List for 1961/62  Models ES2, 50, 88,99,

650 Std & DeLuxe) states the following on page 66:

part no. 18684   Air cleaner (state colour req'd)  All singles

I would have thought that this would have been a popular fitment for all bikes going to places like Egypt, Iran, and/or Australia

It is not that dusty here in Northern California but I would like to fit one

Any information would be appreciated

Mike, I have one buried in my shed, never had time to find it last year but when I do I'll see if I can get some made up in stainless.

The thread is imperial and will also fit the Amal Mk 1 626.

Just not had time to get out there.

Hi Neill

 

i haven't checked the parts book presumably but they would be similar on a wideline?

Will be interested to see what you have.

cheers

Iain.

Hi Iain,

Hope all is well down under.

I was thinking of starting a thread: 'Wheel building by candle light.'

Anyway, back to the topic: I bought this filter from Martin Bratby, several years ago. He told me he had an Amal proto type air filter for singles somewhere, eventually he found it and I managed to persuade him to part with it.

I had it in my hand about 3 years ago while doing some shed organising so I know it is in there.

It is basically a pancake filter but the pancake is very slim. You would need to make up your own filter material. I have promised this before but a priority to find next spring. I don't mind being reminded next April.

When found I will photograph it on a Model 50 and as a stand alone. If there is any interest I will see about having some made up in Stainless.

The slim gap between oil tank and inlet is about the same for both F/bed frames and this will fit on the slimline. Therefore...

Neil:

It appears that there is some (small) interest in the air filter that you have.

Let us know when you have posted it and then if you are going into production.

Thanks

Mike

Mike,

Will do and as I said to Iain, give me a reminder round about April if you have heard nothing.

For 2018 it is a priority!

With the current supply situation re Dommy barrels  filtration has become important. I made that decision 20 years ago with the 99 and now have exellent compression and no wear . Absolute performance is now secondary to reliability and keeping the bike on the road for my last few years in the saddle.

Quite right Robert, looks like I'm going to have to put my hand in my pocket again and have a filter made as a template for the club, as I did with the engine plates you all know about.

Got a lovely pair but just about to give them away down under. Originals too. Shame you didn't ask me last August.

I too asked this question a while back now. I have tried various types of filter with a view to modify ing, but with no luck yet. This is one of those things that the club should invest in if an original can be found.

I have a slimline and a wideline ES2 and know at least 3 other people that have expressed an interest in fitting an air filter.

The Norville filter box can work,especially now we know of a filter that will fit in it. It is a bulky faff to fit and expensive if you buy the carb adaptor and rubber connector (which is not a good fit on the carb ring).Its done the job, but if it were possible to fit a rubber hose and a pod filter thats what I would do, but very narrow space.
