Hello! Im gonna start my first time build soon. Engine kit I'm thinking of deciding on is a Grubee Skyhawk 66cc. Plan on putting it on a cruiser of mine. What I'm wondering is that my cruiser wieghs like 60-75 pounds or so. I want the thing to go fairly fast and I'm wondering how this weight will effect its speed. I live in Denver so im at a high altitude and I weigh about 140lbs. How fast should I beable to get my bike going? I will get a CNS carb with the engine kit as well. Thanks! Very stoked on being part of this forum.
