Yes it id from Doug Coffey at Head Quarters in Sombro Ontario. It doesn't really seem to want to fall off but the get up and go is around 3k , I'm been on the rear wheel of a few twinkie's doing a hard pass, if I had a horn I'd be beep beeping them out of the way.
I'm not much on the technical stuff on it but I'm pretty sure you can get the specifics from the site http://www.head-quarters.com/ . I know he's building a couple great bikes at the moment.

Thanks for the Link. I think the only thing that makes em a little weary on doing this is the adjustable push rod adjustment....... Everything else looks pretty straight forward

I'll check them out and see what they have

if you decide on the andrews I have done quite a few in stock evo's and shovels(not the 27) the 27 will make an improvement but it will really wake up with some head work later on down the road I've been prety impressed with theese after head work,and a good exhaughst,the opening and closing rates are geared towards lower compresion engines and they run cooler temps
