Top of pretty much every page has a notice about the photo posting issue which hopefully will get solved soon.  Right now you need to use a 3rd party like Imgur to host and then post link here.

I'm not a fan of the caps held by a ring...  most likely it's a wire ring and you'll have to push the cap down into the fork tube a little to see and remove it with a pick tool.

That is great help many thanks &  a soak in some penetrating oil & i will give it a go 

If the rubber caps are missing and/or water got in there, it can be a real bear to do that job.  Link with picture of clip www.partzilla.com/product/yamaha/3J2-23183-00-00

I've had the caps stuck tight, got them knocked down enough and the ring removed...  and then had to drill and tap center of cap and to use a slide hammer to remove the cap.  Not fun and caps might get ruined.

i need to do the seals & refill with oil as one is leaking , can i do this without taking the tops off ? 

If it's rusty under the rubber cap you might need to tap it down to get the wire ring visible to pick it out. They're a pain if rusty. Gotta be careful. Set the bike with front wheel suspended & Spring will be under tension of sorts so just tap it down & let it come back until it gives up & comes right out. I don't think the cap goes down far before touching a very slight step but enough to release the wire clip. We had bad cases of rust when used on the farm. A design that should never have been used in my opinion. Think dt175 had that too about the same years.

It's a tough job alone, much easier if someone can push down on the cap while you remove the circlip. Alone, I've used a wood clamp and 1x1x4" piece of wood to push down the cap while removing the circlip.

You do need the caps removed to do seals.

Sorry think Mark & i are typing together again haha.

Definately a bit rusty hence the penetrating oil but if i can do the seals and refill without taking them out then that will save some headache.

On those by memory the handlebars go across the top of the forks, so in desperation you could remove the clip & then sit the bike on the floor for extra spring pressure pushing on the caps, even apply the front brake & push down/forward. The caps will pop up to the bars.
Be very careful but think i'm right.
Had those forks & clamps on my DT1 for a long time many years ago.
One thing i forgot, but Mark might've mentioned--"[loosen the top clamp]" as believe it or not its enough to stop the cap jumping up from its seated possition if still tightened fully.
