Hi - dug this literally out of my shed.  :D

Picture has dimensions. I can get it tumble blasted at work but would have to slip the guy a couple of quid !!

Cheers

Are you sure it will fit though?  I will PM BryanJ and ask him if he knows- failing that I can make measurements if you wish

Cheers

Would it work by plating using zinc without a brightener?

Hmm The purists would scorn upon this !! Maybe ChrisR knows why they are satin chrome. If I remember correctly, I had a 400/4 cam cover bead blasted way back and left some old chromed hex head rocker shaft retainers in which came out a nice  satin chrome finish, Still have those in my junk and they have never corroded (in almost 25 years) , so maybe that's the way to go.

Cheers

I've seen chrome plating before polishing that had a very satin appearance, don't know if that is a natuaral state or a specific process characteristic.

If so it's conceivable that a thin plate would be difficult to finish effectively and could have originally been left unpolished on the early production line.

They plated the starter motor and clutch covers though in bright chrome and they are thin plate?

cheers for everyones thoughts on this

Yamiya sell them as 'no shine type'

Cheers Steff,

In the copy of the parts manual I have there is a different part for K and K1 the K should be 315-300-010. The later ones are 315-300-020  (Protector Muffler). maybe the interim genuine late true K0's had bright chrome.

I seem to remember Chris saying too that they should be satin chrome but he told me he had two NOS ones and the satin finish was different on both. Looking at the pic of Kettle738's early bike (14 frame numbers from mine) they look satin. Also the 'Dick Emery' K0 on the front of MCM Feb '71 looks like satin.


Wonder why the price from DSS has rocketed on these - I thought the 20 quid each that I paid was expensive at the time.

Just glad I started my bike when I did and placed a massive order with DSS and stored the bits under my daughters bed (no she is not pleased with this 'pile of junk' as she calls it  ;D ) Don't think I could justify the cost of those parts now.


Cheers

CB750 / MCM Jan 78 Article

Hi,

Somewhere in the dimmest deepest past I read that you can bead blast the CB750 exhaust heatshields to make them look like the satin chrome of the early K0/Sandcast bikes. I have a brand  new bright chrome set of these but seeing as DSS now charges 135GBP plus VAT for a pair!!!! I don't want to blast them unless I know its going to work out OK.

I seem to think it was in MCM Jan 1978, which I do have a copy of somewhere but in the deepest bowels of my loft somewhere.

Cheers

Hi Pete,

I used a rotating contraption to rotate the part whilst plating. I used a brass slip-ring and carbon brush and holder off a washing machine to conduct the current during rotation. I used a lab power supply in constant current mode to control the plating current. I used the plating solution at 23 deg C I also wrote an Excel spreadsheet to work out the surface areas to get the correct current and used 100mA/sq inch

Best regards,

Ash

Hi Steff,

I already have both DID made rims new from Silvers before prices went up but they have the DID verbage on them and made in Indonesia.

OK it's not a Sandcast but Sandcast's don't have the same magic with me as other folk. We never had them over here so they could never have been the bikes we ogled at as a schoolboy (Well I was a schoolboy then). But mine is supposedly from the first elusive batch of UK bikes made in Oct '69 so I don't mind spending that little extra on it. I am not in it for the money. It's just my hobby restoring it to as near original condition as I can afford. (and one day riding it at last).

Cheers!!

Ash

Bryan   - Re Rim - Its one of those elusive k0/Sandcast parts - like the front hub which is 4mm wider than all later ones. Bet steff knows about it though,.

Cheers

Hmm Pete the pictures come up when I view it.

Here they are again

The wheel rim one is for my K0 - trying to establish if it is the early rounded type - Bryan?  Steff?

Cheers

Just looking at a June 1970 MCM mag with the test of the 750K0

No adverts in there for new Honda bikes but Honda dealers in there were Rex Judd, Chisholms, Fordhams and Read Titan were saying they could supply new Hondas. The reviewed bike was a candy ruby  red K0 reg ,YLY70H. I was also looking at the Feb71 MCM which has Dick Emery on his Blue/Green K0 on the cover and inside, reg BYU762H. Honda dealers in this edition were Palins motors. Rex Judd, Ken Ives and Chisholms

The Nov 74 edition has the road test of the K2 and compares it with the K0. The bike was VPK108M. honda Delers in that were Ken Travers, Harry Wood, Chishoms,Rex Judd, Ken Ives, Victor Devine, Bill head, Millers, Tippetts, PFK Ling,Sid Moram, Harry Gill, Hummingbird motorcyles, Henstocks, Vale Onslow, Fowlers of bristol, Cusworths, Denis McHarris, Fordhams, Ryes of Fulham

Prices from Rye's in this mag  Cb500/4
