Damage to the end of the crankshaft was my main concern too. I did fabricate a bracket out of angle iron to mount to the crankcase and then sat my dial gauge on that to measure any run-out. it seems to be fine but I forgot to take any photos. It seems to be ok but I won't really know for sure until I fire it up and it's under load. I'll re-jig it & get a photo done. If the worst comes to the worst, I have a few engines spare but most need rebuilding in one way or another.

Normally get my gaskets and a few other bits through Graeme France as like Aaron says, he may not be the cheapest, but you know that the parts will be good quality.

Filterman - I've waited years to get a garage like this sorted out. It's only a single but it has power & light although there are normally a few bikes in there so you have move things out and around to get jobs done. I seem to spend as much time moving stuff out of the way as I do working on the bikes. Unfortunately the 'kettle' is a fuel jug so wouldn't want to be drinking out of that  Cheesy

Aaron - I'll try and make notes of any differences but I think you've listed the main ones and it does look like this bike has been modified quite a bit over time so has probably lost some original bits along the way - look at the Chinese front master cylinder & levers for example. My 1st CB-1 came with the same canister type rear shock & even had a bracket mounted to the frame to take the canister.

The Front brake was seized on solid so this was removed (eventually) and stripped for cleaning and rebuild. The pistons have come up fine with a clean & polish so I just need a new set of seals.

Here’s the main damage. It looks worse than it is and there is no play or obvious damage to end of the crank as a result. You can see the bent brake pedal which will also need to be replaced.

The clutch cover was removed and binned and the sump dropped for cleaning and inspection of the bottom end of the engine. A replacement flywheel & woodruff key have been fitted and while I was there I pulled the clutch to check the condition of the plates (all good).
There was some discussion on the Facebook page about using the £10 Chinese gasket sets off Ebay etc. The previous owner had bought a set and gave them to me with the bike but here are some photos which should explain why I won’t be using them.

Aaron - I know that's an NC23 pickup cover but I haven't removed the CB-1 cover yet  Grin

The first job was to get it on my homemade ABBAish stand through the front engine mounts to raise the front end (my ABBA stand is too wide for the bench). The plan is to start at the front and work my way back.

Something that definitely needs to be replaced is this exhaust – it looks like something that should be fitted to the underside of a Nissan Micra, not the side of a bike. It doesn’t look home made either as the headers aren’t standard CB-1 so I have no idea where it could have come from. Fortunately I have a decent original exhaust to fit.

Since the demise of Photobucket, there doesn’t seem to be many people posting projects on the forum so I figured I’d start this thread using Flickr to host the images & hopefully inspire a few of you to do the same.
Ok, so here is the latest project a CB-1 mk2. Although I’ve worked on a mk2 before, this is the first one I’ve owned, although it was never really planned for it to come into my possession. Back in the summer it was posted on the Facebook page and the owner was looking for some help getting it back on the road after a minor crash. The bike had gone down on its left hand side but what caused the damage was that it went under an oncoming vehicle which smashed the clutch cover. As he was fairly local I offered to pop over and help him make a list of parts needed that I should be able to supply from my own stash of bits.
As the parts list grew and the amount of work and money mounted up, he decided that it wasn’t worth repairing and that he would sell it for parts. A deal was struck and the bike was wheeled into the back of the van and sat in the shed for quite a few months until I was finally able to get round to sitting it on the bench and looking at it. The plan was for it to be a little project over the Christmas break but life in general and my other bikes had other plans……

The plan is to go through the bike sorting out any issues and get it back on the road again. It’s only going to be a clean-up and repair rather than a full on restoration. Sure I’ve said this before about other projects….

I would always prefer to fit a locking cap on a road bike but the racing (keyless) cap would also fit

I always think the CB-1 is quite a small bike but the old 400/4 looks tiny by comparison - almost like a modern Chinese 125. Still love them both  Smiley

Cheers for the reply. I meant Stick coils (Coil On Plug) rather than the original coils though. Looks like you're using Dyna Coils which are very large
9  General Category / Photo Gallery / Re: Story of one CB-1 on: January 05, 2018, 08:45:20 AM
Love what you're doing here but I've got a few questions.
Any reason for not using stick coils? (would take up less space)
How are the NOS injectors held in place on the rubber inlet manifolds? (normally they are fitted into a threaded hole)

Good luck with this and can't wait to see the end result

Welcome to the forum and that's a great collection you've got there, but then I'm biased having owned a few XBR500's in the past Grin
11  General Category / Tech Corner / Re: insulators on: December 11, 2017, 08:49:24 AM
I've used the Chinese ones and they work but sit the carbs a bit low meaning that you have to push the airbox forward to fit the 2 mounting bolts at the front of the airbox. Bit of hassle but doesn't cause any problems or leaks once done
12  General Category / Tech Corner / Re: Fuel line with 180 degree turn on: December 04, 2017, 08:49:24 AM
I used most of a 1 metre length of hose and just went from the tank back to the frame cross member and then looped it around the shock (cable tying it in place to the frame) and back to the fuel pump. Not ideal but an easy solution!

Hi Randy,

I've sent you an email

If you can't find one closer to home then I have a 2nd hand one here in the UK. Also used on the NC23 version of the CBR400 (88-89)

Have you checked the main 30 amp (green) fuse mounted next to the starter solenoid?
Follow the wire from the +battery terminal if you're not sure where to find it and the fuse will be under the red plastic cap

Does the motor turn over on the starter? If so check the handlebar mounted kill switch, they are known to corrode up
