I have a 1990 FXR 1340. I have purchased a remote oil filter holder. My question is, on the front of the motor on the brake lever side There is a mounting point on the later models which is a thread in the Engine cast. Can I drill and tap these points or will I end up in the oil jacket?
Hi, yes they can be carefully drilled and tapped. There is no oil jacket behind that area but you may go through the crankcase into the flywheel compartment. Don’t panic, use heavy grease when drilling and tapping to keep chips out of the engine and space the mount outward about 3/16 to compensate for the cast in boss found on the later crankcases. They also sell a vertical oil filter mount which will bolt under your front rubber engine mount. Wrench Safe,
