1975 Honda CB360
« on: July 08, 2008, 07:36:19 PM »
I know this really isn't the place for twins but I figured we were all motorcycle enthusiasts regardless of what we ride.  Besides, there really isn't any good place for twins.

I bought my first bike, 1975 Honda CB360 for $75.  I found out the camshaft was broken where the points and advancer connects.  I replaced it, timed it, and it started right up.  Rode it around the block a couple times, adjusted the points and it rode even better.  I tried to start it up the next day and nothing.  I would get power to my gauges and it would sound like it wanted to start but nothing.  I took off the alternator cover and gas poured out of it.  I found out that my float was sticking, so I cleaned my carbs, put them back on.  Started it again, and only one cylinder was firing and the RPM's kept skyrocketing.  I changed the oil and found out that there was gas in the oil.  I'm assuming also because of the previous issue with the float.  After that, it was running really good.  I was sitting on my bike, and a buddy adjusted the headlight and I lost power to everything.  There were two fuses that I had to replace.  One of them was blown, the other too but was wrapped in aluminum foil.  I guess to keep the circuit open.  I really don't know where to begin.

Would it maybe be a bad ground?
Since the aluminum foil kept the circuit open, do you think it could have burnt a wire?

Any suggestions on where to start?

Welcome aboard   :D Quite a few members are familiar with the "twins" so they should be able to help.

As for the gas issue, you should shut of the fuel petcock all the time when the bike in not running. My bike is rebuilt top to bottom and I do too. It doesn't take much to make the gas leak out all over the ground or fill your engine.

Now, The aluminium foil thing. That will bypass the fuse and certianly may melt a wire or two. Sounds like the PO was tired of replacing fuses and decided to do that. There is probably a short somewhere which needs to be fixed.

I suggest you buy a repair manual for the bike and start chasing down those wiring gremlins before they get worse  :D

Even going though the wiring looking at it around the frame, fuse area and headlight bucket you can find a bad wire or an exposed one touching the frame. Also check the battery and ground connections too.

 Good luck, Matt.

There was a recall about the wiring harness.( in 1975  ;))
 A clip was added underneath the tank mounting rubber on front left.
 
 I have one if you need it.

Check into the cam chain adjuster issues with the 74/75 360's also.
