    @Walney-Reptiles There are upgradable bearings?

      @Calum well i say that what i mean is you can change the top bearing to taper bearings instead of the standard ring bearing

        @Walney-Reptiles Not without changing the the yokes/bearing cup.

        I done it cause I fitted USDs. But otherwise, no. Or I'm sure it could be done, but what would be the point?

          @Calum my dt is fitted with tapper bearings top and bottom with out modifications, tapper bearings are able to cope with greater loads so generally last longer.

            @DTR-NSR Cool, hit the geezer up! I didn't know it was a thing.

            My DT was stolen and ramped. Forks bent, wheels bent, bearings in the head tube was fine. They are robust enough. Obviously Taper has its advantages.

                              @Walney-Reptiles well with your setup i would recommend some 28mm - 32mm carb. for example a mikuni tm28 or a keihin pwk 28. im running a keihin pwk 36 on my dt but i have a 170cc kit on it. its still too big for the bike

                                          Project Update

                                          My forks arrived today

                                          Please welcome my WR426F forks 😉
                                          They are in decent nick for £150 they have Adjustable Compression Hardness on the bottom and Adjustable Dampening on the top, Bearings seam to be a perfect fit all i got todo is but a spacer under the bottom of the bottom taper bearing 😉

                                          Sorry for bad photos
