It cost me $1700... $1200 if you don't want the seat attachment. Yeah, it's on the pricey side and hopefully he'll lower the price some day.
Area P exhaust would look ugly on it so I went with HR1 slip-on since it's compact and will wrap the headers in black. Will paint partial of the radiator but not the fins part. Perhaps later I'll order a full black radiator from China (a bit skeptic of parts from there). I have the Driven mirrors on order for $250. A bit costly for what it's worth, but looks the best and totally adjustable.
Haven't received the kit yet (2 weeks) but I'm talking to Josh about modifying the front part since I won't be using it as a back seat. I'm assuming you would need to cut the back part but I have a sawjaw for that job. Not an issue. Will update.
Since I had time today I ended up installing the Factory Pro jet kit and tuned the carbs. Also changed the throttle tube so less twist of wrist to go WOT. Runs smooth now with a bit more pull.
Here's the HR1 slip-on installed.
