Installed on my TT500 engine. I was super impressed with the detailed install instructions included—it made the swap really straightforward. I had tried some 12v stator conversions to my TT500 in the past, but they never delivered enough even power. But with the Vape system I can finally run batteryless! The lights do indeed pulse at idle if you have the headlight on though. I use an LED daytime running lights, and they are bright at idle when the headlight is off. My only complaint is that the ignition coil requires some fabrication to get it to fit in the stock location. For over $600, you think they'd include a mount for it. But everything else works great!
