Hi guys,
I'm building a cafe racer from a very unloved CB400f. I'm considered replacing the stock swing arm for something a little more "sporty".
Any suggestions?
Cheers David

Hi both,
Thank you.
You have confirmed my thoughts - if it isn’t broke don’t fix it.
However, before trying to start the engine I will clean the carbs and rebuild. Visual inspection, two bowls are missing one screw and on inspecting the bowls have significant residue in them. I don’t want to run the rubbish into the engine.
I will get a the cam chain bolt repair kit. However, I will need to extract the broken bolt first.

Hi Guys,
Getting near to the end of stripping the current project.
Electrics are shot so I haven’t been able to start the motor, however I have managed to get the starter motor to turn the engine over. Compression test are low ~60psi across all cylinders. The pressure goes up to ~125psi when oil is added to the cylinder.
Low values could be due to motor still idle for years, cold test and cheap compression tester.
Also the cam chain tensioner set bolt is broken. I have no history about the bike so I’m assuming the worst engine wise.
Next step:
1. Fix cam chain tension set bolt - do nothing else and get the engine running
2. Do a top end rebuild, possibly with a 466 kit and install new cam chain
3. Do a complete engine rebuild
I’m taking the approach of test, research and repeat before splitting the engine for my first rebuild. I welcome your thoughts on what would be next step that is sensible.
The rolling stock is solid but rough. But the front end has been changed to a cb250n. I have sourced hubs and forks from the USA and will return to stock wheels.
So while deciding on the engine component I have much to do on the rolling stock.
Thank you in advance
David

Hi Ken, thank you for your advice.
Question. Why do the front forks need to be raised by 1/2 inch above the yoke?

Thank you Bryan,I thought that I may need to make spacer to align the sprockets. Also before investing in the refurbishment of the frame I will get it checked for alignment. David

Hi there,
I'm trying to identify the origin of the Comstar wheel that came attached to my next project. [ Guests cannot view attachments ] [ Guests cannot view attachments ]
From my research, I believe the wheel is from a Superdream CB250N. Before I commit to reusing this wheel, I want to be certain of its origin and compatibility with my CB400f.
Concerns are:
1. will the rear suspension need to be changed to longer shocks?
2. by eye the tyre appears to be off centre by 1cm
3. also the drive and rear sprockets don't appear to be inline - again by eye.
The question to the forum is - has anyone fitted this type rear wheel to a cb400f and if so - what adjustments had to be made?

Thank you.
As I said earlier, a previous owner did a mix’n’match job.

Thank you all for the kind welcome!
The weekend has been a busy one - cleaned and started to dismantling the first of two project bikes.
You can see that the bike is in a rough shape. Given the bike has been modified already, I'm inclined to make this into a cafe racer style.
The great unwashed:

Impact of a good wash and the start of dismantling:

I'm pretty sure that the Comstars's are from a CB250N; happy to be corrected. Also the handle bar and clocks are not original and at present I cannot determine their origin.
The engine appears to have good compression. This is based on turning the motor over using the kick start. However, given some of the more obvious additions and omissions I'm inclined to rebuild the motor.
I will post progress and when I get stuck - ask questions on how to proceed.
The trick for me to complete these projects is less haste more speed! A quote from Walter Tivey - my father. It is a pity he isn't around to help, he was a master locksmith, tool makers and blacksmith (old school trained). He would have enjoyed getting his hand dirty on this bike!
Speak soon

Hi BryanJ,
thank you. I will download the manuals. The plan is to read and read some more before going beyond the basics clean up for the new projects.

Hi there,
new to the forum!
Honda 400/4's are rare in Australia so I'm reaching out to you guys in the UK for advice and encouragement. I just got my 400 back on the road after it sat in the shed for nearly 20 years. Iqbal (my wife) bought me this bike soon after we migrated to Australia from the UK. I will never sell this one (picture attached [ Guests cannot view attachments ] ).
However, getting the bike back to being road worthy inspired me to attempt another bike. I was lucky and found two 400s for sale and the seller was located close to Adelaide (home town). Bought online from picture only and I probably paid over the odds but I scored two bikes with clear titles.
When they turned up one has 350/4 engine and the other appears to have CB250N front end. The good point, both have original headers that looking in go shape. I have enough out of the two to restore one to original stock specifications, while the one with the CB250N front will be made into a cafe racer.
The goal a full restoration of both - hopefully, I won't need to do too much with the engines and the plan is to rebuild over winter (your summer).
I will keep you posted.
Cheers David
