Doms CB550F1 project

Not that long ago I was groaning at them being £75! 😡

It's hard to justify £130 to the 'bank manager'

😂😂😂

An alternative would be plated ones on the front to match the rear? Would they be good enough to replate?

The DS ones are BZP aren't they, mine are too far gone and even then the tine involved plating 40 spokes and nipples with my small kit makes the DS ones price attractive

I tend to agree Dom, even with a set in good condition it would be quite a tedious job. Never done a set myself, just bought a replacement stainless sets. Time to talk the “bank manager!” 😂

Here's a question for Bryan or anyone else that knows the answer, I picked up a cb550 hub from Bryan last week which is the version without the flats on the speedo side, what is the real difference if any when used on a single disc set up?

[Bryanj]

Single disc none at all, you use all the same bits in same places speedo drive is driven by the chrome plate and bolts

Cheers Bryan, what was the change for then?

[Bryanj]

Probably cheaper to produce, less machinig time

OK, final question, what was the purpose of the machined flats that were seemingly not required?

[Bryanj]

On the first CB 750 the speedo drive had two turned down flaps that engaged with the slots to turn the drive gearbox and the chrome trim was flat, aparently the speedo needle wandered due to not positive enough drive so honda modified it and i guess just did not get arround to altering the hub drawings till years later

Thanks Bryan!

Today is fork servicing and polishing day!  I've had them all apart to find the lower tips of the stantions are worn a fair bit, I've never seem the. Like this before, are they toast?

[Laverda Dave]

Philpotts could possibly bring them back up to spec with the hard chrome plating. They will probably ask you to send them to enable them to have a closer inspection. Like everything else their prices have risen by a huge amount recently (likely as a result of the chrome plating industry being licensed into oblivion). I paid £280 for my 400/4 set a month ago including the two fork top nuts. £10 return postage is included in that price.

Is it leaking fork oil or is it a cosmetic issue, if its leaking oil then hard chroming by Philpotts looks like the answer.

If it's purely cosmetic can you  live with it or cover it with fork gaiters as a cheaper alternative.

[DomP]

It's only at the bottom of the stanchions so not swept by the seals and totally out of view, I think I need to check them for straightness as that's surely the only way they can wear like that.  No oil leak at all.

[McCabe-Thiele (Ted)]

Could it be the forks have in the past been dry of oil or is it a bend in the stanchions that has produced the bottom wear marks?

[DomP]

Well actually one side was pretty low on oil and both were very dirty, I don't think they've been serviced for years as its been off the road for a long time
