    hey im new to motored bikes and need some sugestions. does anyone know anything about the 80cc jet engine from king motored bikes? is it a decent motor? its only $129 so its a good price i just wonder if its going to last and what i could do to get the speed to be a good 35+ mph? i live in Key West FL. so there are no hills and the island is small only 2miles x 4miles. i want something thats cheaper and cooler looking then a motor scooter.any help or comments would be great.

  2. get a smaller rear sprocket.
    a 44t can do 28-32mph,so go a size or two smaller than 44t = 38t or 34t.
