Thats great Aaron.80cc wow! I run a 49cc with a few mods,and it does me pretty good most of the time.However I always feel like I could use more power.The shift kit you mentioned I'm unfamilar with. How many gears do you end up having? AS far as fit goes in your new bike, were theirs a will theirs a way!! I have a front wheel drive trike that came out pretty good. I had some head scraching,but it came out,& best of all its reliable. I like to think of it as my bicycle truck!!! lol Remember paitence is good,take your time, Its no fun to be 50 miles in the middle of tim buck to and break down.Let me know how your build goes and most important have FUN!!!
