hi everyone im new to this whole scene and quite a noobie when it comes to these gear box set ups and different company engines and whats crap and what isnt. i am quite the gear head and want to be more frugal so i want to get into this motorized bike thing... as soon as i sell my jeep lol anyways ive searched the forums but found nothing. can someone direct me to a good 4 stroke engine kit or a good 4 stroke motor and how to set it up and mount in a frame? any other info on gear boxes or friction drive and this drive and what not would be very much appreciated. thanks in advance!
