I have a new 49cc 4 stroke 5g with dual chain automatic transmission. The gear on the mag rims is a little smaller than the standard bike kit sproket but with my 2 stroke i was going 30 easy with the same gear.. its like I have one speed very powerfull on start actually wants to pop a wheelie. I get to gas it sounds great till i hit like 15mph vibrating really bad like its red lining..sounre sounds like it wants to do another 10mph but somethings holding it back. I have to gas it let off the gas constantly its like i have no play in the middle. Throttle cable is perfect, do i need to break something in somethings deffinately not right..
