I want to get my head done.... So who does good work?

I'm not looking for peak HP but better power everywhere. I want high velocity ports.? I'm running hotcams and a 97mm piston.

Not unless you want to send your head to the other side of the world, maybe ask in the YZ forum.
Just waiting for my barrel to get rebored and plated for my 97mm piston. How did you find the cc increace?

My advice is to go to an enduro or desert race and talk to some of the racers. There's always some dude in the back of a Yamaha shop who is the Guru that you seek. There are a bunch of them in CA I'd wager.

I just did a volume calc.
Displacement Increase = PIE*R^2*Stroke
(97mm/2)^2*60.1mm = 444128ml
444128ml * (1cc/1000ml) = 444.128cc

You can also go to thumper racing's website and find out too.

yeah yeah, i know that. maybe I worded the question wrong. I mean how much better was the power due to the cc increace.
