I recently installed a new head that was worked on by Quenton. It was milled 70-thousandths and the combustion chamber had been finessed a bit. After riding it twice now, I have but three words to describe it: Oh my God!
That thing is now a torque monster. I swear it would climb a tree if it had the traction.
The accelleration only seems to show a modest improvement, but can it climb hills (with my fat carcass) now. I strongly suggest that any WC-1 or NE-5 owner look into having the head milled. You won't regret it.
