  Would not hurt to put fresh oil in and seals, make sure you clean all the gunk out of the fork legs, progressive fork springs would be significant improvement. If you are using new springs would keep same oil weight to start off, otherwise could be over the top. Ask spring suppliers for reccomended weight come to that

  @ryanjimccfc The shocks for all 3 bikes are 410mm in length and the YSS item is listed as being compatible for all 3 bikes, which means it should be a straight swap for the OEM unit. The YSS unit's also offer adjustable pre-load and compression too, just the same as the DT200/Lanza's units just without the external reservoir, so you are getting pretty much the same spec as a used 200 unit all in one package. Plus I think the YSS has a stiffer spring over the original shock? So all_in_all it's a simpler upgrade with less hassle of fitting and mounting the res. If you have the cash then I would go for a new and improved shock over an old used unit everytime. https://www.ebay.co.uk/itm/YSS-REAR-SHOCK-YAMAHA-DT-R-200-1989-2006-SHOCK-ABSORBER-331/183127097768?epid=24009232077&hash=item2aa339c1a8:g:ai4AAOSwRH5XKxXH https://www.ebay.co.uk/itm/YSS-SHOCK-ABSORBER-ADJUSTABLE-REAR-MONO-For-Yamaha-DT-125-R/142012163491?epid=517329238&hash=item211095a5a3:g:2mcAAOSwnFZXUAUJ

  In terms of stiffness I can't say I felt much difference, it feels slightly higher with the R damper.

  Starts to wobble at 70mph and greater when when I suddenly let off the throttle with the clutch engaged? As long as throttle is on, there is no wobble at all past 70mph, although the faster I go before I let off the more violent it gets. All bearings are fine as are swinging arm bearings, bushes etc. Tyres are bridgestone nobblies standard size.

  Burnt the rubber. I have done loads of these in the past, not on the shock of a dt, but when I polybushed my car I had ton take out loads of them and they are never easy.

  @sgt-robuck-5 Just havea look anyway. Poly bushes last a life time and give many benefits.

  @nottsbiker that's exactly what I'm struggling with - I've tried an old wooden curtain pole trimmed down but I can't shift it - absolute pain in the balls

  Looks like the 41mm bit is based on the stanchion diameter so bear this in mind when assuming that WR200 USD forks will fit, they wont as the slider part on these is considerably larger than 41mm and wont fit in your yokes. Also FZR and YZF forks will be a lot shorter than DT ones

  @vtrn_raptor See this thread and speak to @tdrgreg2 He used a set of Aprilia MX 125 USD's which were almost a direct bolt on, just one spacer required. https://dt125r.co.uk/topic/1020/dtdr-build

  I considered the hyperpro progressive springs for mine, but they were listed for the R not the X that I've got. Glad I didn't buy them because mine already had progressive springs in! I went with 15w oil and it's much better now
