I was lucky Smitty (SMC) put my e50 together. He's a great tuner, with the Airsal kit I got and 17mm Amal carb, 3 shoe clutch, of course some case mods and attention to detail, he had it radared at 50 mph after a quick break in. As said, run rich, break in properly and it should be good to go. Good luck and have fun, welcome to the addiction side of Puchs...
