Great customer service By BikeBerry
The first one i got had a problem with a stripped head bolt. Called BikeBerry and they were very helpful. They replaced the engine and within a couple of weeks i was riding again. I've now put almost 200 miles on this engine. Runs quite a bit quieter/smoother than the first engine I had.
