I love the new JSD-3M I just purchased. I can really tell a difference from the first one that I bought with the ground wire. The only thing is now I have about $100 bucks tied up in 2 JSD-3Ms which isn't fun. I could have used that money somewhere else or for something else for my bike. My first one idled at about 1400 rpm's and this one 900rpms with clutch in or out.
