Has anyone found an affordable replacement for the BSA paper element?
I think they are retailing at around £55 for the triangular element.
Just wondering if there is an alternative car element ( possibly a round one) that will fit.
Or - can someone measure the standard one and I will try and find a cheap car replacement. A friend with a Norton commando found an old stock element that fitted his bike on fleabay - he bought 3 for £6 !

I went to my local industrial estate where I knew there was a filtration place that made all types of filters.
I had a chat and the owner gave me a load of off-site of different density foam.
I then made up my own replacement and it works very well , with regards to plug colour and induction noise.

I agree, £55.00 seems a bit steep. I got lucky when a forum member here was selling a new K&N in its box for £25.00. If you don’t mind a used original one, there is one on eBay at the moment for £12.50.

Does the mini 850 filter fit and work
Does the element from surreycycles ( competition gauze ) work? I assume a plate has to be fitted to cover the outside and a bolt through it to hold it to the inside mounting plate.
Is it accepted that paper filters are not really any good for 2 strokes?
I had a spin on pancake filter when I first bought the D14 but soon found out that a lot of oil was getting onto the element especially when tickling the carb.

The problem with pancake filters is that at low engine speeds some of the petroil mix is pumped out of the inlet on to the filter which, if it is paper, rapidly soaks up the oil. I have also found them susceptable to choking with road spray.

Hi everybody
I did buy an 850 mini airfilter to try to fit under the side cover but found getting the internal hole of the filter to clear the intake was a problem so I abanoned the idea.
However, looking at the Bantam pancake filter which I have, and cribbing the original fitment using a BIG rubber band I have now come up with a viable, cheap solution. Unfortunately for all those wanting to know how I've done this, photos are on my camera, but it's in the shed, it's late at night, and it's my bed time. Photos tomorrow folks.

Very interested to see the pictures Don.
By the way, where are you based? I am only a few miles from junc 11 off the 42.

Hi Again
Please see attached my photos of how I fitted the standard Bantam pancake filter to the side panel.
From the pancake filter I used the rear plate and a piece of inner tube cut to suit and hooked it over 2 of the 3 hooks on the toolbox inner plate.
This is my initial stab at holding the filter in place which is similar to what BSA did with the triangular filter.
As Peterg has mentioned there is always an initial back flow towards the carb as the piston decends. Hopefully the air filter won't become saturated in petrol oil mix since the reverse pulse has to travel up the inlet tube then turn 90 degrees. Time will tell

I've never known the oil to get back that far

I'm in the process of doing this to mine.Looking at it once the side panel is attached theres very little area for air to get into the side panel into the air filter am I missing something?It seems to work ok and has quieted the intake roar down from the pancake filter but seems to have knocked 5-10mph off my top speed I'm guessing this is due to the restriction.
What's 7/16 in mm again?

Hi SM
Your comments are very interesting about loss of top end performance. My B175 originally had a pancake filter which I dismantled and used the bits to install the filter into the side panel as shown earlier in this thread. I think I will reassembel the the pancake filter and see how it runs. Also, from your comments - where did I put my ear plugs?
