Title: There is a CB750F god
Post by: JamesH on May 20, 2019, 04:22:46 PM
Somehow managed to pick this up over the weekend - a NOS CB750F HM392 Silencer.

This was the final piece of the jigsaw for my unrestored CB750 F1 with 2k miles.

More to follow..

  ;D It's funny as you can read through a couple of times and not see the obvious.

Nice find though to complete a bike that's essentially so new.

That really is rare, I have the one from mine in the loft, I took it off just after I bought the bike in 1976 but did not bin it, like a lot of the standard bits I kept them just in case I ever sold the bike.

Cheers

Dennis

No idea how much you paid for it but just after I got my F in 2015 there was a NOS silencer on Ebay That never sold for £300 little did I know then about how rare they were. Hindsight a wonderful thing.  :'(

Nice one James  :)

I noticed this guy has the collector box/downpipe assy  NOS ... Gawd knows if the price is realistic ... I guess that due to the rarity, it probably is  :(

Getting the # 1+3 pipes to complete the manifold is very hard,and expensive

Just shows how times have changed, when I was restoring my F1 I got a complete set of nos front pipes for a very reasonable price from DS, now the world seems to have gone mad, must dig out the receipt and see how much it was for comparison.

I bought 2 full exhaust systems from D.S.S. in 1987, including all clamps, brackets gaskets etc, £148 each plus vat (15%). Put one set on my bike, sold the other on in the mid 90's for £450, thinking I'd done alright out of that. Wish I'd kept the second set now to sell today!  The downpipes/collector on their own were £39+ vat at that point.

I bought  a complete system for my 400 from DSS for less than 400 quid about 15 years ago and 500 miles in 1980 something my Honda dealer wanted 1200 quid for a full system....I bought a Motad system back then but it never sounded the same.

I remember the price for a full 400/4 system in the mid eighties being what Hairy quoted and that's when I bought mine. What happened was that Honda, for some reason, totally  slashed their prices on exhausts around that time ..so much  so that  I thought it was too good to be true (I read it in MCM that they had done this).  It was a massive discount at the time, so that would explain the vast difference in price  between what Dave was quoted earlier in the 80's. Still cost me more than I paid for the bike though  ;D

I know someone who worked for a company that operated landfill sites in that era. One of them near the central UK warehouse and they dumped huge quantity of parts via that route, also sent staff to ensure nothing left the site and was buried while they where there.

I'd guess that spares prices on some things gave them a serious overstock which just costs money to store. If you store and account for inventory long enough then the cost of selling it can't match what you've payed to store it,  pure accounting view just looks at cost versus profit, and says cut the cost! :(

I was told by a very reliable source that when the Honda Service Department in Wollaton Rd. Nottingham closed that loads of parts were dumped in a pit that was on site and buried under strict orders that they were not removed off site. Evidently there was a really early CB750 there which they were told was also to be destroyed but it disappeared one night ... this is where my pair of CB750 prototype carbs originated from,  so I wonder what the mystery bike was  ::) ::) Both the Gold and Green CB750 prototypes were on that site at some point. I gave those carbs to a good friend and  CB750 guru  and he identified that they were in fact modified CL77 carbs.

Yes Ash, none of that stuff left the sites at all  :) most of it would go out to scrap.

"Totter's" working the site could smell if it was aluminium,  ferrous or copper as it came in the gate, they'd not miss out on recycling that  ;D

I have a used muffler (original CB750 F1 HM392 silencer) in mint condition, get in touch if you are interested.

(Someone was wondering in some other thread if this is still available - yes it is / May 2021)
