Guys, I just got mine today as well. It looks even better in person and the prototype as well. The pipe is really popular and I had a hard time getting one for myself.
The shift point does change with the new pipe (vs the VR 12) and your 2 speed shoes may need to be tightened a little bit from engaging too early. We tested the VR 12 Plus with all kinds of engines, from JP's, Sirios, OS, Novarossi and Picco motors with great success. So far it has worked well with all the engines we've tried.
