Works (Sirio) after market head
 

Just want to let all the Works (Sirio) guys out there know the Trinity Phatt head $35 at amain for the Novarossi bolts on to the motors. The reason I post this is I asked arround for a bit and no one could tell me. Trinity holes are drilled out so it fits with no mod. I just rebuilt this motor and it always ran on the hot side with the 8 fin head (B3) so I think this will help.
