Anorak's Corner / replacement swing arm for CB400 1976

« on: June 22, 2021, 03:11:12 PM »

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

CB350/400 / Cb400f project #2

« on: June 07, 2020, 09:41:26 AM »

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

New Member Introductions / Saying hello for Australia

« on: May 02, 2020, 04:15:48 PM »

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
