CB350/400 / 400/4 Carb connector
« on: September 17, 2012, 10:40:37 PM »
Due to slightly heavy hands I am now seeking to find a plastic interconnecting tube (small plastic pipe with 4 O rings).

Does anyone have a spare one lurking around?

Any offers of help much appreciated.

Thanks in anticipation,

Rick

CB350/400 / 400 Carb O Rings
« on: August 28, 2012, 05:09:21 PM »
Does anyone know the sizes of the 2 O Rings required for the jets? I know that the overhaul set is available but it seems rather costly when only the O rings are needed!
TIA

CB350/400 / MOTAD Fitting
« on: August 13, 2012, 07:44:09 PM »
I am embarrassed to be posting this ...........Who thought fitting an exhaust system to a bike could be difficult?

I am attempting to refit a Motad M4H system, have made several attempts to fit the pipes then the silencer, then tried fitting the silencer then the pipes, all met with failure! The bloody thing came off some time ago but now refuses to go back on.....The best I can get is 3 pipes to fit sucessfully but the last one is way off target. There only seems one way that the pipes will align for the silencer but then the silencer is way off line for hanging on the bracket.
 
Could someone please tell me the best way to get 6 individual items to live in harmony!!

Glad no one can see me blushing as I hit the Post button!!

Thanks and enjoy sniggering at my apparent ineptitude!

CB350/400 / 400/4 Tacho drive
« on: June 29, 2012, 09:45:55 PM »
My refurb of the 400 is going relatively problem free, just finishing the engine build and I have just found a most annoying problem that I can't seem to fathom out, I am hoping it is not an act of total muppetry on my part!!!

On attempting to replace the tacho drive gear into the rocker cover I dont seem to be able to get the guide sleeve far enough into its hole to permit the oil seal to be fitted correctly. I have checked the hole - No obstructions. It came out when I stripped it all down and it dawned on me...should I have fitted the drive from the inside of the rocker cover prior to refitting?  !!!

I am embarrassed having to put this in the public domain!!!

Wincing...Expecting a barrage of flak!

Thanks

Other Bikes / CJ250T
« on: January 11, 2012, 10:18:43 PM »
Hi,

Asking on behalf of a mate....Has anyone got a cam chain tensioner for a '78 CJ250T or knows where one might be available? He tells me he is struggling to find some spares for his restoration. Is there interchangeability between this and other models?

Many thanks

CB350/400 / 400/4 Seat
« on: December 12, 2011, 10:02:56 PM »
Hi,

I am about to commence the refurb of a 400/4 that has been sat at the back of my garage for several years, not too much work required but I will be replacing the seat that is fitted, providing I can find a decent replacement. It has a considerably lower front than the rear, I guess for those with shorter legs!

Is there much interest out there for such a seat? I have never seen one advertised anywhere before.

CB500/550 / On the road after many years of resting!
« on: June 30, 2011, 10:32:14 PM »
Hi All
At last I have managed to finish my latest rebuild, '72 500/4 frame with '78 550 motor and on its first run out to get an MOT I found that 3rd gear was nowhere to be found, just a false neutral. Can anyone offer any advice?
Other than that all was well, a gentle run to the garage and back (the long way round), I had a smile all the way, not sure whether that was due to the bike being so smooth, the sunshine or just wind!
Next up is the 400/4.
Thanks in anticipation of an easy fix............I bet there isn't such a thing for this one!!

CB350/400 / Alternator cover disc
« on: September 06, 2010, 06:43:23 PM »
Has anyone seen a small HONDA plate/disc that is on the alternator cover advertised anywhere? I cant find a name for it anywhere! I am guessing it is a lightweight pressed disc. It is secured by a couple of screws, well I am assuming that as I have 2 small holes in my alternator cover!

CB500/550 / Which Sprockets to use - 550/4
« on: September 03, 2010, 07:33:15 PM »
Hi all,
Just coming to the end of a restoration and now need to consider which sprockets to use. Is there any great benefit deviating away from the standard 17 tooth front and 36 tooth rear?
My research shows that there is an 18 tooth front available and that the 500/4 had a 34 tooth rear sprocket, can anyone tell me of their experiences of mixing sprockets.
I am after a bike that will cruise well and not after a record 0-60 time!
Thanks.

CB500/550 / Brake pedal spindle
« on: July 24, 2010, 07:33:29 PM »
Hi all,
Rebuild nearly complete of a '72 500/4 frame with '78 550 motor, but having fitted 4 into 4 exhausts from a 550 K3, I now need to tinker around with the brake pedal so it clears the outboard pipe, does anyone know if there is a longer spindle fitted to any other bike that may ease my problem. I need the spindle to be 30mm longer than standard, or is the spindle from the K3 longer to get over the difference in the exhausts??
Hope someone can help before I go cutting and reshaping the pedal.
Thanks
Rick

CB350/400 / 400/4 Ignition question
« on: April 05, 2010, 11:15:08 PM »
Help required again please guys.....I have decided to remove the electronic ignition fitted to my 400/4 and fit it to my 550/4 as I will be selling the 400 before long. Can anyone tell me if the points cam is the same on these 2 machines? I have a points assembly on a backplate but dont have a cam for the 400.
Hope this makes sense,   Thanks.

CB350/400 / Looking for headlight rim
« on: December 28, 2009, 11:24:51 PM »
Hi
Coming to the end of a refurb of a 77 400/4 which has been at the back of the garage for many years, all I need now is a headlight rim and a brake caliper. Is there a rim from another model that might fit?
Can anyone help?
Thanks

CB500/550 / Tappet covers - Disaster!!!
« on: October 12, 2009, 03:42:33 PM »
After finishing rebuild I decided to check tappet clearances one final time and found to my horror that 2 of the tappet covers wouldn't shift by more than half a turn, they had only been fitted a few days!! After much consternation, frustration and cursing I removed the camshaft cover totally and carefully cut the offending items in such a way that they could be removed.
Unfortunately, the threads within the camshaft cover are partially clogged with broken tappet cover thread which was crumbling and causing it all to jam up, I am not able just to hook out the broken bits as it all seems virtually welded in!
Anyone know if 30mm taps are available to hire? Or any other suggestions to get around this.
If push comes to shove I do have another cover but that will need to go for vapour blasting before use, hoping to find a cheaper / easier option first!
Thanks

What is it? / What model is this from?
« on: July 07, 2009, 10:55:26 PM »
Hi
I have a pair of side panels I bought but then discovered that one of the lugs appears to be 90 degress out. Firstly I thought it had been tampered with but there is no sign of any disturbance to the lug.
Does anyone know of a SOHC model that these could be from? They will be heading back to EBay as soon as I find out!
Thanks
Rick

CB500/550 / Seat covers
« on: June 15, 2009, 11:35:35 PM »
I have read that seat covers are easy to fit, although there may be a problem with fragile tabs.......What do you use as a seat trim and where can I get it? I have never seen anything advertised other than the covers!
