Fuel (gas - petrol) Tanks, Side Covers and Air Box / Carb inlet Rubber Treatment to soften with Reofos 508
« on: February 22, 2015, 07:04:28 am »
My video here: Works on nitrile rubber (ie Sandcast/K0 inlet rubbers ) don't believe it will work on PU (Sandcast/K0 Air box 'trumpets').


Immersion 18 hours at 70 degC in Refos 508 in a waterbath heated by a 'slow' cooker on top heat

General Discussion / Letter to Honda UK and vacuous reply.
« on: January 02, 2015, 03:35:58 am »
Recently, I wrote the letter attached to Honda UK. Posted it by snail mail and got no reply for several weeks  so tracked down a direct contact email after much hassle and emailed it. I got the reply below just before Christmas, described as "the most vacuous corporate flannel I have ever read." I am going to follow it up in the New Year.

Please don't shoot me down in flames if I am incorrect on anything in the letter ... I was only trying to do my best! for instance I can't be sure that the Vic bike in Honda's museum's 'ducktail' seat  is a repro one, it may well be a NOS one for all I know. Think I am correct that later replacement K1 seats had no security feature on the holding screws and the originals had  'bruised' over thread ends though  : see
 http://forums.sohc4.net/index.php?topic=143715.msg1634982#msg1634982

BTW I already have a Yamiya seat for my K0 .. it came off  eBayUK by a strange route from a Dutch company  ::) via Wales.  ??? There was a torn up label inside of it's packaging that was printed 'not for resale'. So I am really doing this for the benefit of others on here in Europe.

I  will keep you posted on any developments and a Happy New Year to you all  !

General Discussion / Honda Museum Sandcast. Which seat fitted?
« on: October 29, 2014, 06:22:14 am »
A well known part dealer in the UK and also Yamiya's main distributor, who have just set up in the UK, have been told they cannot sell  items in the UK which are logo'd Honda. However, in other parts of the world Yamiya's seats and covers are sold without restrictions. I have agreed to write to Honda on behalf of the two Yamiya / PMC distributors here in the UK  explaining that this situation is unfair. I did write to them in 2009 but their excuse back then was that the Ducktail seat is a 300 superseded part to the K1 version, so a suitable seat was still available from Honda. This is no longer the case however because the K1 --300-- part is now NLA from Honda. One bit of 'fuel' to my argument is that the Vic World sandcast, which Honda have in their museum is, presumably, fitted with an 'aftermarket' cover but I need to make sure of my facts first.
There have been 4 ducktail Yamiya seats on eBay UK over the last week or so (suspect something to do with CMSNL) and I managed to bag one of these so I am doing this really  for the other poor UK souls / agents.

I did ask Yamiya if they would consider supplying the UK with seats/covers without the 'HONDA' logo printed but they told me the minimum order from the factory to have this omitted would be 50+ seats / covers.

Sold for $13k + Buyers Premium,  looks like a steal to me at that price!!

I know someone who may (should) have bid on this.

Anyone on here know the bike's history or comment on it's originality?

That price makes a nice change from the eBay overinflated prices. But I am in the wrong continent for that!!

Published Material / Edward Turner (Triumph M/C) Visit to Japan in the '60's
« on: June 29, 2014, 01:15:50 pm »
Edward Turner of Triumph visited Japan in the 1960's and his verbatim report here makes interesting reading. Not strictly sandcast related I know but gives a good insight into the demise of the British bike manufacturing industry in the late '60's.

The Edward Turner article scans are quite big so I have added to 'Dropbox'.

Hope you can view OK, let me know if you have any problems.

Chrome - Anodizing and Other Metal Finish Procedures / Vic World Article Spoke Finish
« on: June 04, 2014, 05:17:29 pm »
In this Vic World article  linked below, it is stated that he nickel plates the wheel spokes. I can't believe he would deviate from original spec. Or was it just a misprint? What was the factory finish? I have a really nice condition '69 CL350 front wheel with original finish and the spoke finish looks more like nickel than BZP.

As Kettle738 point out, we reckon all Honda Spokes are BZP though and ageing and polishing on old wheels can make them all look slightly different.

General Discussion / David Silver looking for a 'Sandcast'
« on: May 06, 2014, 02:03:19 pm »
David Silver of David Silver Spares in the UK is building his own museum of Honda's and recently bought the Bob Logue collection during a tour of the USA.

He recently sold his only CB750K0  (Gold)  Diecast to a UK journalist (James May) and is looking for a Sandcast for the new museum in Leiston, Suffolk, UK.

I suppose a World MC remanufactured bike is the obvious choice but may be out of budget range.

 He asked me  to ask around to see if anyone is selling one.

Here are some of the USA acquisitions :-

General Discussion / Cafe Racer Programme
« on: March 25, 2014, 12:58:35 am »
Just watched an American  programme on TV, Cafe Racer where they cut up a perfectly good '69 750, that the guy had owned from new to make a cafe r. Cut up the frame, cut up the (presumably wrinke) tank, chopped off the top of the 'Rhino' horn with the clocks still attached and threw the stock instruments into the trash. Probably just done to shock but I really must stop watching rubbish like like. Thing is they have features on USA junk yards which simply amaze me. All we have here is rusty old rubbish that people want a fortune for on Ebay. Presume the bike was a K0 and not a Sandcast.

Cheers ... AshD
