      @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

                                  The carb looks tall for a DT, did you try fitting it already? Maybe only the gas linkage mount will need changing.

                                    Should be okay, I don't recall there being height clearance issues when fitting the VHSA. Be good to see how this fairs up.

                                      Previously fitted a PWK 32 carb to a 2003 dt and the carb is quite small pictured next to a Mikuni TM 30. Fitted it to a modified 2003 dt inlet manifold, throttle cable outer needs shortening by 30mm carb end and with a warm air filter rubber fits over.
