We had done some M8 heads for a 114″ for Kody at Voodoo bike works. He sent me over the dyno sheet on it. Wow! Pretty crazy for what was really done.
Specs are:
Our head cleanup port with valve job and surface.
Stock flat top 114″ pistons
Tman 216 cam
Stock TB and injectors
Vance & Hines X pipe
Was tuned out in AZ.
Green run was without tuning.
