Title: Truely Amazing Product.
Review: I had been using an Amsoil 10-40 synthetic in V-Star 1100 and it seemed OK, but the gear changes weren't the best. When I had the bike in for service, they changed the oil and when I got it back, the clutch felt like it was slipping and the engine was noisier then usual. I'm assuming they put a convectional Yamalube oil. So I used this Mobil-1 20-50 VTwin oil. OMG! I never thought oil would make such a noticeable difference, but it was instant. The bike ran cooler, quieter and the shifts were crisp and smooth. The 50 weight looks like molasses coming out, but works great in a v-twin. Highly recommend.
