    @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
