70cc DAX motor only going 15 mph need help
Hello eveyone, this is my first time posting I hope someone can help. My bike is only getting up to 15mph. I have tried a few things but it still not getting the full power. It is a dax 70cc. It starts up fine but when it gets to full throttle it just seems like it can go faster but something is holding it back. My next thing I guess I could do is clean the carb and gas tank.
