I need help. First I have never used a forum so I have no idea how any of this works. But that's not my problem... I have a cf moto z6. It will let me get up to about 13 mph and then it won't let me do anything until it gets down to about 10 mph and then it let's me speed up again to 13. I replaced the fuel filter, spark plug, cleaned the air filter and nothing has worked. Idk what else to do. Idk if anyone else has had this problem. Of anyone could help me that would be awesome.
