so i bought the bike a couple months ago really liked it but decided to modify it a bit by changing the color to a yellow eith a camoflauge green black and purple metalic color style i rebuild the whole motor, stador and CDI included... but how do i adjust my gear box for some reason its too loose and to downshift i have to bring it up then down...another question would be why does it leak if i changed the cracked o ring it had just beneath the front sprocket cover... last question for now would be why doesnt my signal lights work yet the front lights and rear lights actually do work...???
