Blaster Vito’s +3mm Stroker Crank (no spacer must port cylinder)
This crank is not drop in ready. It does not come with a spacer plate kit. The spacer plate does not allow the full potential of the crank by limiting port timings raising thr cylinder rather then alloeing the ports to utilize the extra travel.
Your cylinder must be ported for this and your head modded to accept the extra stroke.
This is a common mod for most builders and standard practice.
