Honda CB750K5 Restoration by Royhall

[royhall]

Thanks Ken I may come back to you on that, but no doubt it will be months before the chroming is back. Good luck with the foot.

Any idea on how much the tank costs to be dipped. I have a lovely tank but it has some pitting near the bottom next to the seam. I want to see if it leaks before I have it sprayed and the aggressive nature of the dipping would be a good test, no good putting petrol in it, finding it seems ok, getting it sprayed only for it to leak after 6 months of use.

If it leaks at least I’ll know and maybe I can get it brazed or have the small section cut out or just bin it.

For mine it's £57 plus vat mainly due to the extra work required to remove all the heavy rust inside. They use a heat cycle method to remove the paint and filler, then chemicals to remove the rust. Then it's phosphated to prevent flash corrosion.

No filler on mine, had it since new, inside is immaculate, just the rust pitting that’s the problem.

Thanks for the info.

I know the 750 points covers have gone through the roof Roy but your really going to get that chromed? TTR400 does some lovely alloy ones engraved with the old fashioned Honda wing, cheaper than buying a new one these days and he’s coming over later this year so he should be able to bring it over to save postage. If you wanted it shiny maybe ask him for a bare alloy one and I’ll mirror polish it for you FOC.

Chromers say they can straighten it out, so considering the price for 18 items I thought I would let them have a go. If it's crap it was heading for the bin anyway.

Who are you using for chrome these days Roy? I switched from $%££% to Prestige and so far so good. Pity 'cos $%££% excellent when I 1st tried him out but deffo went downhill last time I used him

[royhall]

He's the same guy Ash. He did the few chrome bits on the Bomber okay recently and the 350F before that so hoping for the best. Price seems okay though. You don't happen to have a spare set of 750 oil pipes for sale do you.

Roy - I'm curious. Do they clean it in a pyrolitic oven to remove the paint / de-rust?

[royhall]

Not sure what it's called James but it is a heat process of some sort. They did my GS1000 tank when I was having problems with it and the process removed all the paint/filler/and attempted solder repairs. It came out really well, but they wont do older British tanks as they are soldered together and just fall apart.

Roy… I’ve been keeping quiet coz I’m such a long way away, but yep, I have a serviceable set of oil pipes off my K2 - though they really would benefit a recondition.
I’m away from home right now, but if interested will post pics.

Price, if interested, upon receipt the postage costs + give me what you’d have sold them to me for…

Let me know,
Simon

[royhall]

Thanks Simon. Yep post some pictures. Could do with one that's immediately serviceable as it's pretty hard to get them redone with the black cotton braiding. I have had them made up before but in stainless braiding. If the pipes are good I can always polish up the ends. Thanks.

Steve / Roy… apologies as could not post these pics on PMs - so everyone has to suffer.
Anyhoo; Roy, it’s a while since they’ve seen the light of day, and nope, they’re not black braiding but high pressure black hose. Which is fairly cracked in places - hence me renewing ‘em some time ago.
Anyways, have a look, and depending upon what Trigger has to offer get back to me.
Cheers,
Simon

Wrt the Braided cotton finish on the oil pipes, I sheathed a clear breather hose on my old Kombi in heat-shrink braiding - and am pleased with the results. (Obviously you’d want to modify the ends a bit better!)

As I rebuild the K2 I may try this on my SS Braided pipes - if it looks / becomes shabby it’ll simply be a case of cutting it away. Worth a try?

Philpotts did a great job on my fork top nuts, they were really chewed up. I sent them in with the fork top tubes and rear axle.  Great thread, enjoying reading it, good luck.

Thanks for that Simon but I now have a good used set in the black braid. Good of you to go to the trouble of posting some pictures. Cheers.
