Intermission!

Got to ride this beauty doing some catch up lessons before my mod 2.  Great fun that bike.

That's my other red Honda in the background.

So, no start. First thought, fuel. Checked the bowls, got a bunch of fuel all over me for my troubles. I'd cleaned and checked the jets, so they were hopefully OK, so I moved on to spark.

Took out one of the plugs, held it to some exposed metal... and... no spark.

Lots of electrical debugging - I thought running continuity tests would give me some indication of a possible short to ground leeching power from the battery which I had charged a few days before.

Eventually I thought to check the fuses:



That's probably not a great sign.  Fuse replaced, further tracing of this and that. Took the headlight off to look for exposed wires shorting.



That's probably not great either.

I'm sure I've missed pics for some steps, including putting the carbs back, plumbing the fuel tank in etc. But here goes:

Step 0. Get it running.

Carbs off, check the bowls. Tiny amount of residual fuel, but no varnish. Nice. Looks like they had been drained. Fixed the cracked breather pipe.



Next up, fuel tank. Added some new fuel and shook it around a bit.  Drained into jerrycan through coffee filter. Lots of grit and gunk. Glad that didn't go through the carbs.



Spark plugs: these had obviously been running rich, but  were gapped OK. Cleaned them up and put them back. I have replacements, but wanted to see if these were OK.



Points: looked OK to my untrained eye. One side had an obvious gap, the other didn't. No glaring corrosion on the wires. Someone with a deep hatred for screws had obviously been in there though :(

I wanted to do a project log for my own documentation, to show my project off to any friends who may be interested, and to share the journey and any interesting tips with anyone else who may be interested.

I'll not put dates on these first set of posts, as it's been a long while in the making, and fairly slow progress, but it keeps me busy.

Firstly, the bike:

'75 CB400/4. Red. 2 1/2 engines, one seized, the other in the frame. Original wheels, forks, bunch of other bits and pieces. Bought without seeing it running (smrt).





Naked!

So I was struggling to get the rear wheel dampers out of the hub, as well as the bolts themselves, so rather than risk destroying the hub I handed it over to a local tuning and machine shop here in Edinburgh.

They were able to remove the bushings, but to do so they drilled into the hub from the back to get them out.

Have they ruined my hub? They assured me that it won't have affected the structure/performance.

Hi all,

I'm Kenneth. I'm an Aussie who decided to move to Scotland for some reason, and ended up in Edinburgh.

I picked up a CB400/4 a while back and have been slowly tearing it down for restoration. It came with a spare engine (which I expect was the original as it matches the paperwork), the original wheels & forks, and a bunch of odds and ends.

Looking forward to restoring it close(ish) to it's former glory. I have a million and one questions, some of which have probably already been answered on these forums but I haven't managed to find the right threads yet.

My pre-teardown bike here:
