Picked up a PCV a couple of days ago. Came off a fellow forum member. It was on a 99'. Remapped and installed. I've read plenty of threads in the past raving about the change in the bike and I always thought, it's not that bad stock. Now I get it. Like a different bike. Like a perfectly balanced carbed bike! I also like the reduced engine braking. Very good bike made better!
If you installed it on your 6th Gen, then yes, it is a huge improvement especially with the low RPM fueling.
