so i swapped back to my stock rockers, i removed the lash cap from the intake, the intake spring felt weaker than the exhaust so i swapped them back to stock. same power, but now if i put the filter assm. back on, i draw way too much gas (black smoke). mix cannot fix it. so i removed the breather. sounds different, and starting to sound a bit weaker. also put stock muffler back on, same, just quieter. starting to wonder if it isn't a sleeper! when i say same, i mean no noticeable differences
