The filter cartridge is used on Norton Commandos so despite what our competitors say they will always be available
Unlike most car engines, classic bikes suffer from very poor oil filtration, leading to comparatively rapid wear of the major engine components. Gauze and/or felt filters will trap larger debris but allow smaller particles, down to micron size, to circulate causing continual wear. Modern 20/50W detergent oils are designed to carry particles along to be effectively filtered out. Fitting an up to date replaceable cartridge filter will give an older motorcycle modern filtration levels allowing much greater engine life.
Now available as a kit, this filter system comes tailor made to suit each individual model allowing easy fitting. Everything required for installation is included in each kit along with full step by step instructions. The Cartridge is also a 2CV Citroen equivalent.
This is a proven modification with many hundreds of kits sold over more than 20 years.

BSA A10 MAGNETIC SUMP PLATE & ST./ST. STRAINER KIT
BSA sump plate kit comprising a cast & machined aluminium housing, a magnetic sump plug, St./St. gauze strainer, gaskets & St./St. caphead screws & washers.
This is a very good addition to the lubrication system of the BSA twins using a magnet to attract microscopic ferrous particles that otherwise circulate in the oil causing wear.
We have made this as a finned aluminium casting as the rough surface & the fins helps to cool the oil as it passes.
The addition of a sump plug means that the sump can be easily & quickly drained after the bike has been left for some time & the oil has drained into the sump
Also fits A50/A65s, C25, B25 B44 & B50
