Check the listing for details. BSA A7/A10/A50/A65all years sump filter kit SRMSF1. Condition: New. Listed at 76.84 USD. BSA A7/A10/A50/A65 fits all years sump filter kit. Can also fit the Ariel Huntmaster but you will need to use the original gauze plate. Complete kit comprises of CNC machined alloy plate, stainless steel drain plug with strong neo magnet and copper sealing washer, stainless steel gauze plate, gaskets and stainless steel fixing bolts. The drain plug allows quick and easy oil changes without the hassle of removing the complete sump plate, the magnet in the drain plug removes deposits from your rings and bores, these deposits are the main cause of engine wear, so easy just to periodically remove plug and wipe clean magnet. Note our kits have the drain plug situated in the correct position, some on the market I have seen the magnet too close to the pick up pipe and the magnet holds the ball bearing down in the scavenge pipe, resulting in oil not being able to be returned to the oil tank. Drain plug must be fitted facing rear wheel.
