Great work Ace! Looks really good!
I think the best part about it is that it is very affordable, as far as the stuff we have produced so far. It's the least expensive overall package we have made.
It uses the cams that came with the bike, and still retains the auto-decompressor function to protect the ES sprag system.
It retains the hydraulic roller tappets for no adjustment requirements.
Works with the stock piston, or the 535 flat-top piston.
The rocker system significantly increases the lift, and adds about 8-10 degrees to the effective duration between the .050" lift points.
It flows very close to 200 cfm.
It has a 32.8mm inlet tract, which will support 6000 rpm, if the rev limiter is re-set to a higher rpm.
Torque will be increased all thru the range, and the rpm range will be increased.
Everything about this head's specs say it should be the centerpiece of a UCE that can do The Ton, if the EFI can be re-mapped to suit the need, and a free flow exhaust package is installed. This head gives the capability, at the lowest price that I know about. The owner already has the Power Commander V and the Autotune, and some experience in mapping it. I think this bike will give us some very good performance and valuable feedback info.
Re-posting the pics, since they got pushed back on the last page.
