Speed after installing 80cc motor...
I installed a 80cc motor in place of a 49 cc motor, expecting that I would be going 35-ish or so. State law in MA says engine can't be bigger than 49 cc and max speed of 25.
I discovered I could reach speed of 30-ish or so, this bike is heavier than usual. However, that felt pretty scary because everything was vibrating and screws came loose all over. I'm more comfortable keeping 20ish or so. I like to look at the scenery; what's the big hurry?
I was afraid cops would pull me over for going too fast, but it doesn't look like that is going to be an issue here.
