I've been running the PV3 (NOT the PCV) for under 50 miles and it idles fine, runs fine, and the map is dialed in. Sounds a lot like user error - 600 miles to tune a single cylinder motor is insanity. aRacer and PV3 are both fine choices. I would not personally run a piggyback box such as the PCV. For reference, I'm using the a 32 mm ported throttle from a Honda Streetfire (old model); the only issue I had was the stock battery not being strong enough for the 181 kit.Look in your Installation Manual wich comes with the Kit, Camshaft Timings are provided by Kitaco.
I am sorry but Wicked_VFR is right, ditch the PV and get a Aracer Mini 5 with the AF1 AFR Modul.
I am running a complete Neo Kit with 34mmTB, Hindle Exhaust and all the supporting Mods, i have tried everthing to get the Bike run well with an PCV/WB2,
search for my Posts here in the Forum, drove around 600 miles to build a Map but never got it runing perfect. After installing the Aracer Mini 5 / AF1 the Bike ran
instantly better, building the Map only needed around 1hr riding Around.
