Hey Will, good to hear from you. I just pickup a STorm EX with YS 120. I figured its time to jump in and get my feet wet since I've been with 60 size for the last 30 years. Anyhow, I had originally ask the question concerning the many versions of the 120's and wanted to hear feedback. One gentleman really spelled it out in describing the upswingSo in referrence to the Webra's, the fewer moving parts, the less headaches? I've read countless horror stories on 4-strokes but at the same time, very positive comments. I guess what it all boils down to is care and maintance. Once in while, you'll get a lemon but not often with YS motors. Are you currently running Webra motors?
