I have a puch e50, I just put a boss pipe on it and have a high flow air filter. It’s a 1Hp model. Iv tried running a few different jests with a 12mm bing carb and a 2.22 atomizer. With the largest jet I have a 79 the plug is only a little wet. The top speed I am getting is 24 mph. The bike runs good other then this top speed I’m open to suggestions of why it is running so slow.
