im running a stock motor and carb on my moby 50v with a simonini pipe. (im waiting for the 70cc kits to get in at treats. or any where i can find a one!!) i want to get a dellorto carb but dont know what would be best a 15/15 sha or a 19mm PHBG ruber mount, both with the shorty intake. i really dont know what would be best. please help!
