I think DanielG had one of those. He pretty much destroys it and the dealer in one of his blogs.....
I've read that, and heard his oral version. Sounds like a complete disaster for him, and definitely turned me off. I remain optimistic that the company's success (its grown a lot since I first started following them) is a sign that they are improving quality control.
When they started out they were using a Lifan 250cc. I don't recall if their first models were using an overhead cam version and/or if this current push rod OHV is something they have had made since. It would be a lot more appealing to North American buyers if they could get a 500cc push rod single made along the same lines.
