the Z12R is a good motor as it is picco.
The rest of the LRP linup is SH which are junky motors, not to mention they snap cranks and throw rods as if thats what the were designed to do.
They make lots of torque but the power curve of the motors isnt broad at all, you cant expect much from a 140 dollar engine really. Its about like the CEN .46, makes alot of torque cause of its large displacement, power curve is very sad and makes no HP.
