OK this is retarded but i just went out and bought one of the 49cc  pocket rockets and i want to put a larger sproket on the back for a little more torque i want it to pop wheelies and stuff being i can afford to drop it and not the gs this is the bike i want to play with and stunt on you know so if any of you klnow any way to hop up a weedeater motor more or less let me know thanks    ill try to post some pics of it later if anyone wants to see it   Thanks PITBULL

pipe/carb/port the cylinder....i'm waiting for my 47cm bike.....

call/e-   sprocket specialists....they do sprockets

Porting to make that little lung huff, larger carb and pipe to feed and expel that added volume. and a titanium jock cup as a scatter sheild.

um....i can't imagine that thing weighing more than 50 pounds, does it really take much more than you just leaning back to pop the front end up? i'd spend your money at the hardware store buying stuff to make a little 12' bar

it is 92lbs    just leaning back dont cut it i can snatch it up and all but thats kinda nerve recking even at 20 miles a hour when you 3 inches from the pavement    I want it to do it on its on with minimal effort from myself   I and 140lbs and 5-8  so I am not that big of a guy.
