Hey there, i am thinking about what really happens in a shock stroke sequence, Why do we use 4-port piston instead of 3 or 6 or maby 2 port, has it become a industri standard ? How much influence does the port size ? How much is the lift on the shim stack at a impact of 3 M/s ? What is the differens in feeling and performance if we change the lowspeed shims ex. 14x40- 0,20 to 4x40-0,30, ? Why do all shimstacks looks the same ( Pyramid with or whitout crossover)? Would this work ? Piston 4 x 40-0,30 1 x 30-0,25 1 x 24-0,20 1 x 30-0,30 Stop washer 40x 4,0mm Yea i know! i think a lot, but what are all you tuners tought about this. Happy thinking Rob.
