Re: 70cc DAX motor only going 15 mph need help
Skyline- Welcome to the place.
Places to start- Check your spark plug- should be a chocolate brown, not oily and black or grey/white.
Double check the tightness of the manifold bolts and the carb clamp.
Post back here when you do those things and let us know what you find....we'll get yer' motor runnin'!
