                      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.

                                    Hi @jonne123 carbon reeds only make a difference really to fully modified engines when all other mods are done as it is a
                                    combination of all tuning mods matched that makes a difference and carbon reeds do nothing for a standard engine.
                                    I fit them to most engines I build as make them myself as easy to make them and cost around £1 a set to make.
