Has anyone on here had any experience with the replacement fork tubes from DS? I have longer than normal stanchions in my CB750 K1 forks, think they must be chopper parts by the length of them, and wanted to purchase a set of standard length tubes (failing getting the ones I have here machined down and rethreaded - is this an option?). The tubes I need are the earlier types with the 4 ring grooves at the bottom
Any alternative suppliers appreciated :D

UK Pete got some for his K0 and found that the bottom section was chromed where it shouldn't be so he had to mod them to fit. DS would not acknowledge there was a problem when I asked him about it and wasn't forthcoming with the contact details of the manufacturer, so I voted with my feet and got mine from Yamiya, as did kettle738 (Mick)
DS= Made in Italy
Yamiya = Made in Japan.

Don't take the chance with ds, he has not acknowledge the prob so assume it's not rectified
I bought a pair off eBay a few years ago also same prob . If I had of k ow they were also ds ones I could of saved myself a lot of bother

Repro ones forsale in the UK are shite, just get the original ones rechromed by Philpots
-
The ones he's got are oversize Trig, that's his issue!
-
Yamiya ones are OK .. there is a slight change in one of the retaining clip grooves though. Saisei can order in for you.
Agree with Trigger though Philpotts is probably the best option. Don't agree with him on rechroming the top nuts though... I saw some on their stand at Stafford and they looked horrid.... maybe a one-off but would you really display ones like that at a show?

That's not a problem, as I have a pair of old ones from a early K that he can have. If he wants to go down that route ;)

Nothing wrong with my shiny nuts that Philpot did, I always throw the rear wheel spindle at them, when I have me forks and nuts done ;)

Cheers for the replies fellas. I was originally thinking of buying new ones as opposed to rechroming as the price wouldn’t be that much different I thought. I’m actually gutted I can’t do something with the oversize stanchions I have here as the chrome is in good nick. Annoyingly my K6 forks (standard length) are the same but the fork lowers on the k1 have a slightly wider internal diameter so using them went out the window.
What sort of state are the ones you have there Trig? Would they need a lot of prep doing to them prior to getting them rechromed.
Also what’s the going rate for rechroming stanchions these days, about £140 odd?

They are old stanchions but, no prep work needed. Philpots will reverse chrome them. check for trueness and they will look like a new pin by the time they have finished with them >>>>> http://www.sohc.co.uk/index.php/topic,8027.msg52179.html#msg52179

When Philpotts finish with them the quality of the chrome is streets ahead of stock chrome. I had a pair of stanchions rechromed by them for my 400/4 in 1992 and they still look new. Philpotts also check them for straightness prior to rechrome and correct any minor irregularities.
Its a no-brainer for me, rechrome every time.

Cheers guys, looks like I'll be contacting Philpotts very soon then, you lot on retainers or something with them ;D
How much do you want for the fork stanchions Trig?

They are freebies , PM or Email me and we can get them picked up from me by Philpots and delivered back to you. This will save some £££ on postage ;)

Bit worrying this. Bought DS stanchions last year and not got around to building the forks yet. What exactly is the issue with the DS stanchions?
Cheers,
Kevin

I have fitted them to my K2 - the only problem I have is they 'clunk' on bad dips/holes in the road. I posted about the problem and someone replied that its a problem with the DS fork tubes and they had to mod them in some way.
-
Why not pm UKPete on here ? From memory, the problem was on K0/K1/K2 early stanchions where the bottom of the stanchion is left un-chromed but on the Italian made DS ones they were chromed too in that area. The Yamiya ones are correct, so I bought those instead.

Can anybody expand on the 'clunking' that is being associated with the forks? Is there a known reason for this and a solution?
Any reason as to why it is specifically associated with the DS replacement forks?

I think the problem with DS's were that the piston wouldn't fit onto the stanchion ... so if you assembled OK then probably something else.

My forks from ds are for the k0 this has lots of clips pistons and bits that attach to the bottom fork leg the problem with mine was the thickness of chrome would not allow all the pistons and bits to fit, option was remove chrome or some material from the inside of the pistons and bits a major pain in arse
Not aware of clonking but I have not used them yet
-
Thank you for the feedback, if I understand correctly I should be able to build up my forks ok with the DS stanchions on my K4 (less complex assembly than K0?) But the K2-6 type are susceptible to clonking when bottoming out.
Nothing ever straight forward in the restoration game!
-
Maybe its a problem that doesn't relate to the DS stanchions but when I posted about the problems, someone commented that another member had had the same problem and related it to the DS stanchions. Can't find the post now.
If you don't have a problem, let me know and I'll look for another reason why my bike clonks!
