I use one of these on my 350 AJS in the return line along with a magnet that the oil runs over as it returns into the tank;

Works a treat and I drain the tank,clean then refill with fresh oil. Wash the filter and clean the magnet,then run the engine with the return line running into a waste container until the clean oil comes through. Because the engine is in good shape and the tank is newish the oil stays clean for most of the year.As soon as it starts to discolour I change it, I think its working because the engine is still sweet and doesn't use any oil, I rebuilt it in 2011 and its done alot of work since then.

Thanks Jon, do you place the magnet into the filter housing?

No, on mine I've stuck it to the vertical return pipe inside the oil tank as its a steel tube inside the ally tank. The idea is that all the returning oil flows down over the magnet,it does seem to work. You can imagine where the pipe goes in above the filter in the pic.

I have one of these fitted to one of my Cubs:

Oil filters are from a Citroen 2CV

Mine is fitted under the seat as I'm using an under the petrol tank oil reservoir and foam air filter mounted directly to the carb. 

 Among other advantages this filter adds around 1/2 pint of oil to the total volume and acts as a bit of an oil cooler.  It is very easy to obtain and change the filters.

 

Hope this helps,

 

Bruce.

Thank you Jon and Brucey I am impressed by both filter installations. Each just tucks away on the bike.

I find the reduced capacity of having the oil in the top tube makes the oil hot during a trial. 

The additional capacity and position of the filter helps keep the oil a bit cooler.

Brucey I had an engine breather tube arrangement on my Cub similar to the one you have but have recently added a reducing elbow which fits just below the front of the seat with the duck bill vertically down the seat tube, this should prevent anything being drawn up the breather pipe by the engines pumping action as the flattened tube end allows air to escape but then closes shut again.

Need to measure up now to see which type might best fit my bike, it has an airbox under the seat so space for a filter is limited.
