CB350/400 / Where to fit a small analogue voltmeter ?
« on: June 23, 2022, 06:21:23 PM »
I presently have a small digital voltmeter mounted on the handlebars between the mounting brackets.
It works just fine but in bright daylight you can't read the display.

Has anyone here fitted a small diameter Analogue guage -the old headlamp mounted units would be ideal you could fit a raised type unit in a suitable housing?

CB350/400 / What is the right way to check the 400 oil level?
« on: June 23, 2022, 03:53:06 PM »
A really basic question - to check the oil level is this done with the dipstick resting on the casing thread or fully screwed back in?

CB350/400 / Removing the petrol tank without damaging paintwork how ?
« on: June 19, 2022, 08:00:45 PM »
My Petrol tank has been removed several time by me & the PO the tongue seems to have the paint chipped/scratched  in the process.

Is there a safe way to pull back the rear rubber retaining strap to avoid damaging the paint or ripping the strap ?

Fortunately I have not had the tank repainted (yet) so not an issue probably the thick re-paint it partly to blame. 

How do members here remove the tank without causing paint damage?

CB350/400 / 400/4 is popping & banging with poor mpg where to start?
« on: June 16, 2022, 09:29:15 PM »
This evening I fired up the 400 from cold I let it run at between 2- 2500rpm for some 20 seconds then checked the front pipes.

Number 1 & 3 cylinder are virtually cold - number 2 & 4 nice & hot.

So where do I start to diagnose what the problem(s) are please?

An Idiots guide if you will of the best logical steps I need to take in sequence please?

CB350/400 / Running in a new engine after rebuild how many rpm?
« on: June 13, 2022, 08:48:42 PM »
My engine has had a rebore what sort of rev limit is sensible and for how long?
When is the ideal mileage for first oil & filter change?

Came accross this today ----wow.

Cant seem to post the link from the start so you need to rewind -  some great bikes.

Lovely red Honda at 9.43/38.23 looks like an early twin.

Some nice bikes in the last half of the Bike Shed Motorcycle show London 2022- money bling.

Misc / Open / Anyone seen this Yoshimura ?

Ideally my next project will possibly be another 400 that someone has given up on or has a blown engine. This would enable me to use my spare engine & various other 400 parts that I have built up over the last 18 months.

I liked the look of  Nashers 500 & various 550 bits he is trying to sell for a widow - it might be a project too far - not to mention the distance involved. Anyone here know of a 400 at sensible money with a duff engine?

Having seen the Electric Harley Davidson on TV got me thinking about some of the latest technology in electric motors for transportation.
I am an ICE fan - I cant get excited about washing machine based engines but..................

Currently manufacturers of EV's use radial flux electric motors but a UK engineer Tim Woolmer has developed an existing design using axial flux technology. He has obtained 214 bhp & 266 lb ft of torque from an electric motor weighing just 24 Kg now developed to produce 800Nm of torque.

He is currently working on an in wheel design electric motor - imagine that on a front or rear wheel drive motorcycle. Sadly Mercedes Benz have bought out Yasa so the design might not be available to all. (YASA - Yoke and Segmented Armature).

I might be completely wrong here but my memory of resistor plugs is that they seemed to appear at around the same time as carbon plug leads in the battle to stop inteference on your radio & to a neighbours TV. Certainly back in the 1960's you sometimes heard and even saw a crackle on your TV screen when certain vehicles were close to your house.

If you fit a none resistor plug to an engine with no resistor in the plug cap how does this affect the way it starts or runs - is it related to having carbon leads or copper leads?

Does the resistor aspect affect the timing?

I have the Dynatec coils & electronic ignition kit on my 400/4  that comes with carbon type leads and the plug connectors are just a metal connector with a rubber shroud so no resistor.

Should I use resistor plugs (NGK DR 8ES-L) in this situation what effect will it have to have none resistor plugs as I have fitted at present (NGK D8EA)?

I am somewhat ignorant as to what reistance does in the ignition circuit - I've read some articles here & elsewhere about the duration of the spark and how it affects the fuel burn but tbh it's way above my head.

Misc / Open / Bangers & Cash S3 Ep7 Honda S800 Coupe
« on: May 13, 2022, 07:35:40 PM »
I love this series tonight I watched the above episode showing the Honda S800 Coupe.

Back in 1966/7/8 I worked part time in the motor trade. I twice got to collect  Honda S800 Coupes and one  convertable from the Chesterfield Dealer outlet (a branch of Brocklehurst Motors) and drive them to Derby on trade plates - no A38 back then just lovely winding A & B roads. At 6ft 1in they were bit compact but wow did they rev & go!

CB350/400 / Old tax disc holder where to mount?

Yes they do not issue them now but.........................

Where on the nearside of the bike do folk here mount the well expired VEL ?

When I did my dynamic timing a few days ago I did it for 1/4 initially so today I spent over an hour trying to get the timing marks for 2/3 spot on at the same time.
A long winded process as one of the modules was close to it's limit on the clamp screws so undeterred persevered by way of moving the 1/4 module on the back plate then re-timing to 1/4 then again for 2/3 - repeat until you start to forget when it's too advanced / too retarded.

Conscious of not spending too much time with the engine running & not cooling with movement  I made most of the adjustments on a stop start basis. I have it pretty darn close for today - I will check it again tomorrow when I can stand up straight again. It was towards the end of the process that I sat in a chair with the bike lift raised to it's highest position.

It's not an issue when you rev the engine but at idle speed there does seem to be quite a bit more backfiring from the exhuast system than I would like- it's a Motad system what is the most likely cause please?
My carbs have not flooded with no petrol smell evident - engine idles at 1200 rpm whilst checking the timing in the F position.

Misc / Open / Lessons learnt from my 400 rebuild.
« on: April 30, 2022, 09:37:10 AM »
1.You can never take too many photos during dismantling but not everything might have been correct when you started.
2.Keeping a daily log of work done can help with motivation if your enthusiasm wains.
3. Just as important as photos when dismantling are photos during assembly especially of the parts that are hidden after assembly.
4.Take your time during assembly making sure you check and check again.
5.Don't be afraid to ask questions even if you have to wait a day or two for an answer.
6.A clean work area is a must - dog hairs were my problem.
7.The only person you need to please is you - it's your build.
8.When you complete your first build there will always be something you wish you had done better or differently.
That's the learning curve in action don't let it get to you.
