Hey looking to see if anyone has this setup and how it works I have 2012 pro 800 full dyno port system y pipe pipe and silencer works really well no fuel controller riding at 0-2000feet and I'm looking at adding a pa head 12.5 any advise. Thanks

Ive got one on mine. All i have is a Jaws can. There is deffinately a noticeable difference. Adds about 100-150rpm. So youll have to adjust your clutch weights accordingly. I went with the Dalton adjustables. They work awesome. And i there hasnt been any fueling issues. WORTH THE MONEY!

A 12.5 really isn't worth it in my mind. The stock head is 12.1

Helped mine.

And with the head you want it to run about 8050

It is not just the compression that makes hp, it's dome design and squish thickness. Setting the squish up right can make a big difference
