That's looking really nice Eric. Must say though, you started with a way better example than mine was. Don't think I would want to do one as rough again.

Did you get the exhausts from Silvers or are they the originals? When I did mine a couple of years ago I had real trouble getting an exhaust set where the welded seams were acceptable. Just wondering what they are like now as they had loads returned.


Hello Roy
The exhausts came from CMSL, see post above. Since buying them I've heard a few stories about the earlier ones not being up to the mark with poor welded seams, but the ones I've got from the latest batch that have become available are perfect.

Cheers

Glad to oblige Sam. Here is what I started with.
Paint somewhat faded, usual Jardine 4 into 2 pipes, but overall a fairly solid bike and I was well please with what I got. There was some rust, which is to be expected, but nothing too bad at all.  The initial plan was to get it registered and ride it while there was still a bit of summer left, but it didn't run too well, so I decided to crack on with the restoration and dismantle it. Just as well really given the missing oil pipes in the cylinder head!

Apologies Eric, it was my that set off that side track about plugs.

No apologies necessary, I'm sure we've all learned something and here is another pic.

Thanks for all the kind words guys, they make the restoration so much more worth while.

Spot on Eric you must be a proud man ! Mr. Honda's  favourite model too I believe.
Where did you get pipes?  .. I know RoyH  had problems obtaining decent quality ones.
These Yamiya one look the business double skinned headers too. It puzzles me that they can't do 400/4 ones double skinned though.

Hi Ash
The pipes I got came from CMSL, which probably originated from the same source in Japan as the Yamiya ones although I can't confirm that. I suspect those currently on offer from DS are also from the same source.

Cheers

CB350/400 / Another restoration ready for the road
« on: February 02, 2018, 02:35:49 PM »
Hi folks
Here is my latest restoration, a 1972 CB350f imported from the USA. It's been a fairly straight forward job. Take it all to bits, powder coat and re-chrome as necessary and replace various parts with new ones from David Silver / CMSL adding to their already bulging bank accounts, but what would we do without them. A big thanks to both. Phil Denton also provided some lovely stainless components - Cylinder studs, axles and swinging arm pivot to name but a few. More of him in a moment.
The snags, well there had to be a few. On getting the bike I noticed a bent fin on the right side of the cylinder head, nothing that a gentle tap with a piece of wood and hammer wouldn't cure, but then I noticed some damage around the number 3 spark plug. A strange place to get broken fins and also the top of the cylinder stud in that area had taken a beating. Once the cylinder head was off it was easy to see why. It had obviously suffered a seized / broken spark plug at some stage and some clown had tried to drill it out going off center in the process. Part of the old spark plug was still there! Cost of repair, well north of 100 of your best pounds. Plenty of second hand cylinder heads on ebay, all in the USA of course and cheaper than repairing the damaged one except that the cost of shipping was stratospheric. Fortunately DK Spares came to my rescue with a spiffing example, 80 quid all in, result. On removing the original cylinder head I also noticed that the oil feed pipes that distribute the lubricant to the camshaft and rockers were missing. Probably omitted by the same miscreant that damaged the head in the first place. Ebay to the rescue.
The one thing that did cause a problem and delay to the restoration were the fork covers that sit on top of the bottom fork cases. They were a devil to remove, but thanks to those on here that came up with the solution and I got them off without damage. The snag of course is that these components are no longer available and are so thin that a re-chrome would probably finish them off completely. The odd second hand one appeared on ebay in a far worse state that the ones I'd got. Enter Phil Denton into the equation and a commission to make a pair out of stainless. Very nice chap Mr Denton and he likes a challenge. Slight drawback in that he is a very busy man so the components did take some time to appear from his emporium, but well worth the wait and they wont rust. Hurrah!
So there you are, it's all tickety-boo, tip top and ready for the road whenever the weather decides to improve. Hmm, could be a while.
A special thanks to;
Terry Chambers (Racepaint UK) for the paint job
Triple S for powder coating.
My good friend John Edge for the chrome work
Phil Denton (see above)
Steve Lomas (5-one Wheels) wheel building and tyres
David Silver, CMSL and J. T. Marks (USA) for various new parts and DK Spares for the second hand ones
plus my trusted friend Graham Wood for all the help with the spanner work.

Hope you like the end result
Cheers

CB750 / Re: Race cam chain
« on: December 03, 2017, 06:12:57 PM »
Shouldn't be a problem as I use a heavy duty chain in my CB750K3. However, those chains in the pic are around 40 years old, given a choice I'd go for the chain as supplied by CycleX in the USA and even at 100 of you your hard earned pounds its probably going to be a lot cheaper than a 970 / 971 part.

Regards
Eric

All help gratefully received.

CB750 / CB750 Forks
« on: July 18, 2017, 01:31:22 PM »
I have several sets of front forks, those from the K6/K7 models measure 77cm from the center of the axle to the top of the fork tube when fully extended so spring length/compression is not a factor. A set from a K1 also measure up exactly the same, however, another set of the early type forks I have allegedly from a K0/K1 are 4cm shorter. Have these shorter forks come off something else, like a CB450 perhaps as the fork cases are the same as the early CB750 or did Mr Honda in his infinite wisdom make a change somewhere in the production run?

CB350/400 / 1972 CB350F - Oil Filter Collar
« on: January 25, 2017, 01:58:21 PM »
Does anybody happen to have an oil filter collar, Part No. 15423-333-000 that they can measure the length and diameter for me?
These parts are still available, but at some cost, £30.48 plus the dreaded VAT, which does seem rather a lot for what appears to be a thick walled piece of tube, so I plan to knock one up on the lathe.

Thanks
Eric

Thanks guys. Off into the garage now to change it around, not for long though as it's f-f-freezing c-c-cold in there.

CB350/400 / CB350f Prinary Chain Guide
« on: December 28, 2016, 01:27:45 PM »
Does anyone know which way round the two primary chain guides fit in the crankcases on a 1972 CB350f. The photo attached is the lower crankcase with the front of the engine at the bottom of the picture. There is a small hole at one end of the guide, which I assume is to signify which way round it fits, but I can find no reference to it anywhere. With a 50% chance of getting it right the question is have I and which way round does the guide fit in the upper case?

Thanks
Eric
