I have purchased several servos from vh without a issue. The time I had a issue it was resolved quickly. That was until I purchased a sv 50 cc twin from them !!!! The cdi had weak spark on one output, so I sent it back....approx. 6 weeks later after many pissy e-mails they sent me a cdi for a single...today exactly 2months later I received a cdi for twin with the same g.d issue...to be honest i think it's the cdi i sent in two months ago. Lesson learned. I also see now they are no longer selling gas engines and half or better of their servo stock is out!!!
