You may recall I bought a restored CB750 K1, which although looking very fresh and new is not very shiny - the engine cases and fork lowers that should be polished, have had the same aqua jet (or vapour blasting, IDK) treatment as the engine - it all looks new but doesn't shine.
(http://i34.photobucket.com/albums/d144/roycropper/P9060205.jpg)
The fork lowers I will remove and polish during the winter, and the cam cover can just stay there for now, I'm not taking the motor out just to polish or replace it, until I really have to.
However, I was excited this morning to get a box delivered, which contained 3 NOS parts - the alternator cover, gearcase cover ('crankcase mission cover') and clutch outer housing. The gearcase cover alone is £405 at David Silver, the clutch cover £114, and the alternator one is out of stock - so £200 for the lot on Fleabay is a definite result! :)

The gearcase cover has a couple of small marks, which were mentioned in the eBay ad, fair play, I'm torn between leaving the lovely 'new' slightly brushed finish alone or trying to sympathetically polish them out.
I have ordered new kickstart and gearshaft seals, I'll post 'after' pics once the cases are fitted, I'm sure there will be a definite improvement, The removed bits will be for sale once they are off, vgc, but not shiny enough for a 'as new' restoration.
I'm still after the polished cover over the drive sprocket 11351-300-050, btw.

Great score there mate well done. Any chance you could take a couple of close up shots on each cover to show the linished / lacquered finish.? I know a lot of the guys on here would be keen to see...
-
I thought you'd fitted a nitrous oxide kit for a moment there James!, great price on those parts.
-
You could have polished the originals for free. Wouldn't have taken very long from a vapour blasted finish. And now your faced with polishing them anyway. That said you got them for a great price, why not move them along and make a nice profit and polish the others.
-
Thing is Roy trying to get that NOS linished / laquered finish is very very difficult as I'm sure you know. Brightly polished isn't everyone's cup of tea I guess.
-
Meh, I'd rather use the NOS stuff and sell on my existing cases, polished or not. The more original a finish I can get the better for me as I want the bike to ultimately be 'as new' as possible.
As far as photos of the finish go, I had a go, but its not clear. To describe it, the gearbox cover the brushed effect is all horizontal, they didn't bother at all underneath. On the alternator cover, the circular part with the 'Honda' on it has vertical brushing, other than that its all circular, but not at all underneath, or around where the screw lugs are.

That's the finish you get with fine grade "Scotchbrite" wheels and a coat of clear lacquer. Just leave it with the rough cut without using the polishing mops. Comes out well, just like original. And takes no time at all. I know what you mean about the bright polish though James, not my thing either. Belongs on old Triumphs etc.
-
It looks great to me......
-
To explain an earlier comment to James about the linished brushed effect on the alternator cover, the section within the circle on the side is brushed vertically when on the bike, the rest has been done radially, but only as far back as the start of the screw lugs. Between a line around the top of the screw lugs to the casting edge is just raw unpolished. If you look hard at a couple of my photos you can see this.
Roy, I appreciate that I could have got a similar result myself, but I dont have original parts to copy, and if I can sell my vapour blasted parts for similar money 'blasted ready to polish, paint or use as they are' then I have acheived a NOS finish for little outlay and no effort - suits me as I have enough to do already, including polishing the forks and rear brake plate.
More NOS came today, this time lots of little bags from David Silver....

As I've said before, every part made of rubber has aged badly, last week I replaced the fuel cap seal, which practically fell apart. Amongst other bits in there is a battery strap, gaskets for the indicators and a front brake master cylinder service kit, as there's a rubber seal that could kill me if it failed.
Also a set of new tappet covers, and genuine bolts for a variety of places - when it was restored a lot of the lovely OEM, but probably tarnished, bolts have been replaced by generic plated metric bolts with all sots of mumbo jumbo on the heads. The new OEM ones are all polished or '8' bolts. Someone will say that it doesn't matter, but hey, it's my OCD. I'd prefer to have CDO - the same complaint but at least the letters are in alphabetical order.
Also in todays post was a proper clutch centre tool, which has to be better than a hammer and screwdriver..... 8)

Woo Hoo!
I was just popping back to the house from the garage (Ive fitted the valve caps so far, lots more to go) when I spotted the postie on our driveway. A quick check of the letterbox, as I have been doing every day, and theres a letter from the DVLA, this time not returning all my documents again, but containing a logbook! ; :D
Candy is now a 'J' reg, I'm now searching online for someone who will make her a nice black and silver numberplate. Oh, and swapping the insurance from my crocked Sportster.
-
Well done mate. Good result. I get my pressed plates from these guys and quality is excellent.

Get my plates from NowPlates, he has all the sizes >> http://www.ebay.co.uk/itm/Motorcycle-Number-Plate-9-X-7-Black-Silver-or-Yellow-Black-Pressed-Plate-/291593657722?hash=item43e4561d7a:m:mcJqDbvTwFByTkbi0ewMlfw

I used this place for my pressed reflective plates; they also do black and silver ones:
http://www.chestnut-registrations.co.uk/vintagebikeplates.aspx
I also saw a couple of mentions that say the use of black and white plates is now linked to the Historic Vehicle class,
so currently 1st January 1975. At least one of these said the DVLA site and MoT rules hadn't yet been updated to reflect
this, and I can see nothing on the DVLA site. Has anyone else seen or heard about this?
-
This may help, but I will not pass a MOT on a bike that has a black/silver plate if the bike is 1975 onwards >>http://www.tippersvintageplates.co.uk/phdi/p1.nsf/supppages/tippers?opendocument&part=9 VOSA state that a bike/car can display a black/silver plate up to January 1975. Not sure if this will roll over next year.
New rule book usually come out in March/April ;D ;D
-
I'm pretty sure black and white plates are still only allowed for 1972 and earlier. In any case, it looks wrong having black and white on these machines, they had yellow from new. Reflective white and yellow plates were available from about 1967 before they became compulsory in 1973 and people were very keen to adopt the new style as it looked modern. My Land Rover is 1969 and it has it's original yellow plate on the back even though it's a G reg and perfectly entitled to have black and white plates.
-
I first found mention of the change when I visited the Chestnut Registrations web site and got a pop-up telling me the news.
Further investigation found notes of a meeting between the FBHVC (Federation of British Historic Vehicle Clubs) and the DVLA, see page 8 of:
http://fbhvc.co.uk/members-pages/newsletter-archive/_file/200/fbhvc-news-4-15-pdf-pdf/
There are vehicles where the model range life spanned the period when black and white plates were and were not allowed; some owners
may wish to fit black and white plates even if on their particular vehicle they weren't fitted from new.
It's a bit like things like exhaust systems. back then some people binned the standard systems and fitted 4 into 1 systems because they
'looked modern', but now many people are seeking the originality factor. It's a matter of personal taste.
-
The K1 I had when I was a student had a red frame, dark blue tank, 4 into 1 and a Yoshimura cam, and I had no urge to make it standard. How times change.
Anyhoo, I ordered the plate off Chestnut, and insured the bike with Bennets instead of the broken Sportster, after an initial hassle because due to a glitch their system for policy modifications had never heard of the CB750, though I could insure it under a new policy, which I did, fully comp for £80 or so, ironically cheaper than when I was 19 and could only afford TPFT cover. I do want a black and white plate because I can, I know all about the original 1972 cut off because I illegally put a black and white plate on my 1977 T140V. I got pulled for it on the M61, recovering the bike to my mums after I'd headbutted a VW in Manchester who hadn't seen me. The copper let me off with a warning, what he hadn't noticed was that I nearly rear ended his Range Rover because I had no front brake (I had taken off the broken disc), the forks were bent and twisted in the yokes, and the front wheel was shaped like a potato crisp. :-[
Back in the garage today, the first job was the clutch inner cover, that all went well, and was all fastened up again and the clutch re-adjusted, , when I noticed the gasket still on the old cover - D'oh!!! I also took the chance to spray a bit of silver on the kickstart shaft. A nice number 7 bolt went on the kickstart pinch bolt too.

On to the other side, here it is apart. The 911's whaletail makes a useful table.
(http://i34.photobucket.com/albums/d144/roycropper/PB080002.jpg)
I'd swapped the gearshift cover first, big mistake - to get the alternator cover off I had to take the other 2 covers off first, or there was no slack on the wiring. Here I have fitted the alternator coils into the new cover:
(http://i34.photobucket.com/albums/d144/roycropper/PB080004.jpg)
Here it is back on but built into the new cover, before the wiring got tidied out of the way:
(http://i34.photobucket.com/albums/d144/roycropper/PB080005.jpg)
The finished result, the K0 sidepanel is temporary (and for sale soon) while I wait for painters who promise much but do little.
(http://i34.photobucket.com/albums/d144/roycropper/PB080014.jpg)
Once the wife had gone out I pinched her hairdrier, and put black heatshrink over the nasty red connectors on the front brake light switch.
Finally, here are the bits I took off, pm me if you are interested, otherwise they will appear soon on the bay of fleas.

Pardon me for butting in here, but shouldn't the transmission cover for the K1 be a plain specimen. The ones with the cast in gear change pattern were not introduced until the introduction of the K4, at least not according to the Original Honda CB750 book by John Wyatt. However, if you wish to be rid of the plain one, let me know what you want for it.
Cheers
Eric

Strictly speaking you're right Eric. I just assumed Davo was happy to compromise given it's a lovely NOS part..?

I have challenged this claim before with John Wyatt as I have a original UK, 1972 CB750K2 and know of others with the gear change casting and, it is a true statement on USA K4 onwards. Not sure if this was down to Honda using two third party company's to make this case.
-
Trig, possibly a 'parts bin' issue on assembly. Mark Paris in his (My CB Book) points out that there where 2 factories assembling CB 750's.
As Eric's post. Just looked at the John Wyatt CB750 book, (page 73) gear pattern photograph is (K4) onward ? Also the alternator cover on later models had recesses for mounting screw heads.

PS Eric, page 68 alternator cover

You're right, I noticed the gearshift pattern wasn't on the case I took off, then I checked John Wyatt's book, and decided it was a compromise worth making given the lovely NOS finish. If an early case comes up in similar condition, though - I'd never say never!
Interesting what Trigger had to say about the gear pattern marks being on his K2 though, what did John Wyatt say? Frank's K2 for sale has them too, but its a cheapie for him at only £12.5K. 8)
http://www.ebay.co.uk/itm/131577067010
In my partsbook, K0 K1 and K2 all have a different suffix to the part number, the gearcase was the only one of the three covers I bought not to come with a Honda part label. If anyone is looking that close, they are looking too hard, says the sad man fitting the correct NOS Honda bolts everywhere where there already perfectly good bolts.
Tha cases are up on eBay as a job lot, Mr Cheeky Barsteward here is trying to get his money that I paid for the NOS ones back, or as much of it as I can, I'll drop the price if (when) there are no takers. I'd rather sell all three together if possible, so I dont get stuck with anything. If I can't I'll split them, but for those asking after mine, DK in Stoke have a vapour blasted gear cover, without the shift pattern, for only £40, they don't seem to make the distinction as they list it as suitable for K1 to K6!
http://www.ebay.co.uk/itm/331504238061
They also have a used polished one, with the shift pattern, but it seems to have been removed with a crowbar, its broken in 2 places along the edge with the alternator cover. :o
I got all my documents back from the DVLA today, with a note to say the logbook would follow - actually it was the other way round. As a historic vehicle, do I have to do anything each year to tax it?
-
Yes you still have to apply for either tax or sorn annually so that they can check insurance and MOT. 10 Mins on line usually

I got a NOS F2 generator cover from GovnorsBridge Mcs and took a punt on it stripping Ok. The black paint almost fell off so pity anyone with an F2. The finish underneath was the same brushed ally finish as on the non painted version so just needed clear coat
