Well, I spent the day rewiring my 74 550. I have one remaining problem with the electrical. When I reinstalled the harness, I had a remaining plug for the neutral safety system. The plug is red and for the life of me, I can't find where to plug it. I figure I should be able to just short out some of the pins and bypass the safety system. Anybody know which ones to jumper?
Also, cluch is crazy tight. Almost takes two hands to pull in. Clutch is also dragging some. Nice clunk when going from Neutral to first.
Bike seems to work good. Some smoke but I think it is from the carbs needing tuned some. I actually drove it on the road today. Nice little hop in the front wheel at 40 but hopefully new tires will cure it. Bike started loosing power but I pulled over and it came back. Go figure.
Been a super fun project. I highly recommend resurecting one of these old SOHC/4s to anyone!!!
