Head Quarters machine shop?
Anyone ever use them? Anyone ever hear of Doug Coffey? I sent them an email inquiring about there service mentioning that I had Buell heads and that the valves were bigger than standard 1200 heads of that era.
He stated that this. According to there website they have been around a while.
Not that I am doubting his claim. I just want thoughts and opinions..
That may however be asking for trouble..
I'm aware of the valve sizes. We use 1.9" intake and 1.625' exhaust.x
The head design Harley is using is one I developed way back in 1989.
