Half the fun with the pcv is goofing with the maps. You can buy a map switch from them, or make your own for about 2.00. The switch will allow you to keep two maps ready to go at any time.
As time goes on, people will develop maps and share them. A switch like this works as well as the one they sell for 75.00

Your pcv map will be more boring than the pic I'll post. What the pcv does is allow you to select just how much fuel you need based on throttle opening and rpm. Yours wont be this exciting. The pic is from my concours 14 and as you can see, it needed much different fuel requirements than it came with from the factory.
I did not have enough room to show more than the fuel needs up to around 5000 rpm, but you get the idea.
Left side of the scale is rpm. On top, left to right, is how far I have the throttle open. Notice how it will go from being way too much fuel to not enough within just afew rpm.
Notice, too, the negative numbers. People assume new bikes run lean. Yes, at a few spots they are lean. However, notice how many cells have negative numbers that show the bike was very rich. This is why this is A real fix vs boosterplug which wont accomplish anything the machine needs.
If you go to dynojets web site, you can download the software, and their recommended map for your machine. No charge.
Even this is old, junk technology compared to reflashing, but it works really well. The reflash lets them offer so many other adjustment opportunities.
