Don’t.
Buy a new one. That’s my advice.

I agree...
or powder coat the spring and buy a new top bush (still avail new), rezinc the rest of the parts and source a (very hard to find) nos damper part...

You can only do a cosmetic refurb realistically.

I have a good OEM shock in need of cosmetic refurb if standard looks are key?

I've only seen one NOS one come up for sale in 10 years and I bought it and fitted to my bike about 4 years ago.
Not seen one before or since.
Plenty of good after market options though.

I have 2 cosmetically refurbished ones....good for OEM look.
Or get a YSS one if you want a decent modern replacement for not too much money.

I agree about the refurbished units, they are 99% at best just 'cosmetics' when you see them... ...but it is possible if you search long enough to find the parts... as I said the bushes are still available new from yam and you dont want a slack bush(!). Of course dampers can be properly refurbed. ie you can drill and weld in a fitting to regas the unit and this means it is then possible to fully strip and rebuild the damper so you can properly rezinc the parts and fit any seals required, even if it wasnt meant to be done from the factory. This kind of work wont be cheap tho if done by a pro as they dont like extra effort over doing the more east to strip and rebuild modern type. So, I reckon if a person does buy a refurbed OEM unit you do want to know exactly whats been done... defo ask the question of the refurber. ie. you dont want a unit that was a rusty old junker thats now pretty only on the outside... and always check for wear on the shaft. As mentioned above, I have a nos damper and will rebuild one of my shocks as I want the bike to be an 'OEM rebuild', but it took 10+ years to find that damper... I was feeling flush that day tho and I did buy two tho as the seller (old Yam dealer from years back) had two on the shelf in the warehouse and I was gobsmacked to locate them... you have to wonder why they even had these?! But hey I wasnt complaining, none of us who find nos parts at old dealers ever do, we just stump up money they ask. Ive spent way too much on NOS parts over the years, I guess we all have... lol Ok, Yeah, I spose that Im parts hoarding but you never know when you will need things like this, some NOS is just sooo hard to find. Of course, I should really sell the spare one so some one can use it but the last time Yam sold them new they were £375 according to Fowlers so who knows what a nos one is worth now, sigh. A YSS is cheaper than that of course. As usual nos is a mad world and I reckon this kind of part is the sort of thing that only those desperate for a 'fully OEM restoration' would want to buy when an all new YSS would be significantly cheaper and is a much simpler job (ie just fit n forget), no worries or work required etc. But of course there will always be weirdos like me out there who want an all yam bike  lol |

I love a 100% standard LC but I would have nothing negative to say at all about anyone fitting a nice aftermarket shock. I think you'd have to be a special kind of odd to have a whine about that. For a show bike fair enough I suppose.
Having said that why not refurb the standard? Then maybe do a back to back ride comparison. I have a YSS but I may still do that.

I'll do that one day Steve, I just need to do the shock refurb... which means finding a new plater as one of the jobs... hmm....

I'll do that one day Steve, I just need to do the shock refurb... which means finding a new plater as one of the jobs... hmm.... I don't want to tempt fate but I do feel like I've nearly cracked the home plating lark. Mine is actually zinc/nickel which it's supposed to be a much higher level of corrosion protection than zinc alone. I've done most of the bright zinc on the SR125 and the LC now and some of the olive drab and zinc and gold. I did a power steering pump off a guys Sirocco from work in the zinc and gold. That is probably the biggest piece I've done so far. If I can do a bottom yoke in olive successfully then I'll say it's cracked  I love seeing the results  I would recommend buying a kit and having a go. It's not about the money as much as the convenience and being self sufficient but I'm probably about the break even point now |
