Gday guys my father has a 74 XS650 bobber his had it for years been sitting in the shed for awhile now so me and my brother thought we would pull it out and get it going for him for Christmas turns out it was harder than I thought just looking for abit of direction or input if you guys have any.... so it was low on spark got new spark plugs and checked out the points they had seen better days so I brought a second hand set with backing plate and all that where on another bike working fine so I got home put the second hand points in and went to set them up pulled off the magneto casing to realise it had a PMA set up on it so I had to refind tdc the F mark and mark them all back out so I knew where they where did all that set the points up to spec put a test light on was generating power ect now it has a dual output coil on it so I fixed the 2 points wires together and put them on one clip on the coil then I ran a Hotwire from the battery to the other clip on the coil tested it and it was running power through the coil to the points so I gave it a kick it went to fire but didn’t gave it another and it popped out of the carbs 10 more kicks after that it wanted to fire but wouldn’t then all of a sudden there was nothing when you kicked it I’d lost spark to the points got the test light out took the points wires off the coil had power running through it as soon as I put the points wires back on the coil it wasn’t generating power out of the coil I had to move around the points and backing plate to get power to them again I think iv reset the points about 10 times and I’m still getting it to want to fire but it won’t then every now and then I’ll lose spark to the points and have to move the backing plate around to get power back out of the coil again I’m pretty stumped anyone have any ideas ? Cheers
