    @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.

            Oh sweet bud. Sounds very expensive, but if its a job worth doing it's worth doing right.

                          @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 😉
