I received a free 1974 CB360T today. I brought it home, laid everything out and shot a quick video. Plan is to build this into a scrambler.
Thanks for the feed back. I asked an Ebay seller to give the me the dimensions on a XL350 swing arm and found out it was wider so gave up that idea. The engine does indeed have the two punch marks.Fun video, ambitious project. You mention possibly swapping in an XL250/350 swingarm in place of the 360. I have both bikes. As best I can tell measuring them on the bikes, it appears the XL is 15mm wider at the pivot point than the CB. The XL is also different in that the piece of tubing the swing arm bolts through (pivots on) is not continuous because of the structural design of the backbone on an XL. Might be easier to work on offsets and spacers than to do a swap.
Also I don’t know that it’s been mentioned but check and see if that 360 motor has the tensioner upgrade. If it does it will have 2 punch marks, one above and one below the dash in the engine serial number. Without the upgrade you may not get as far after the apocalypse happens... Good luck with it, hope this helps a bit
