Does anyone know if the GYTR head combustion chamber is different from stock?
Trying to determine what the issue is that is causing the binding. I thought I may have installed the piston backward. I installed it with the arrow toward the intake (front of the bike). I believe this is correct.
Any help appreciated, I assembled and disassembled head/cylinder bunch of times today, cannot determine actual issue. I am going to contact manufacturers Yamaha/Vertex/Hot Cams see if I can get any info from them. However, I thought the GYTR head was designed to be run with even stock components.
