Hello, today wanted to vote the scooter of a friend. Is a NRG MC3 POWER DD 50 Year of construction 2005 Setup All throttles outside Exhaust Stage 6 Replica Carburettor Dellorto PHVA 17,5 Clutch Stage 6 Torque Control Clutch bell Stage 6 Air filter Stage 6 two-layer So the following problem, I can not get the carburettor properly tuned to the scooter. I already had the problem with my NRG MC2 LC already with the same gasser. However, this was with my not so big problem with 70 he DR and YASUNI R. Had a large main nozzle in it and then it went on. A 76 main nozzle is too big. With a 72 it runs really well. However only up to about 60 km/h and then it leans and does not really go at speed. Can that be the manyicht that the auxiliary nozzle is too small? Is a 34 in it. And where can I get one of these? at Scooter Attack … it does not exist, only for 19 gasses and Stadler it can order only for the scooter in original. That can not normally be n. On a TPH Bj 2004 we have the same carburetor on it with handmade TT and 70’s main nozzle and it runs perfectly. But on the NRGs the ned. Why? Can it still lie on the membranes? are original, but Kunstoff. Mfg
