Might sound a silly question but I hae an 89/90 husky 510TE which needed replacement crankcases. The ones I got to replace are froma newer design - 1990/91 I believe - have a threaded hole at the back fo the sump for an oil feed pipe (fed from drain plug I believe) As the original bike/casing set up didn't have this and I can't see any other filters or drain plugs in the replacement casings will I need this pipe? I have one (the pipe) but not the drain plug with the oil take off in it. All the other engine parts, eg barrel clutch gearbox etc are from the original 1989 bike Thaks in advance and sorry if this is in the wrong place cheers Matt S
