+The original plan: \\
+Remove the engine plate, fill / drill holes as required, machine the large bolt to accept the 3/4" BSP fittings and weld/braze it in place. \\
+But due to how close the gasket would be to the edges of the plate, the hole positions dictate placement. \\
+So this mod was created instead as a dedicated filter base that would onto the motor mount. \\
+The sketches below were created as a rough design with the final shape being cut to best suit the motor mount. \\
+There is a dedicated gasket face built by dishing out the bulk of a metal plate. \\
+The pipe fittings are threaded into the plate and bolt and sealed with thread tape / crush washers. \\

+A 100 x 10mm mild steel flat plate was chucked up into a 4-jaw chuck, skimmed for a gasket surface, center bored and dished for the filter section. \\

+The bolt was clamped in a lathe and thru drilled with a 11.5mm bore and the ends turned down. \\
+(drill the hole nice and slow to keep down heat) \\
+The bore was tapped to accept the 3/4" BSP connector. \\
+The plate was then roughly mock sketched and cut with an angle grinder, cut-off discs and a file. \\
+The final shape will be done when you can hold it in place relevant to mounting bolts etc. \\

+Then the plate was mounted back in the lathe to turn down the mounting tabs. \\
+This will reduce unnecessary weight and allow the use of the original engine mount bolt on the front tab. \\
+The filter sets there better using the engine bolt. \\

+Test fitting now helps to shape the mounting tabs and locate the optimum position for the oil hole. \\
+The threaded nut was welded in the rear side (having chamfered the nut and rear of the plate to enable a good fill). \\
+The weld was turned down flush and the hole was drilled and tapped for the oil inlet hole. \\
+The motor mount was drilled and tapped for the plate while on the bike. \\
+Then the filter surface was masked off and the plate was etch primed and top coated. \\

+Here's a closer look at the mounting tabs that were turned down to reduce the thickness. \\
+(to allow for using the original engine mounting bolt) \\
+This solid flat steel plate could be thought of as a really big washer. \\
+The oil line connectors protrude through the engine mounting plate and are accessible for connections. \\
