            @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.
