I'm good with a firm shift but don't want anything ridiculous or bone jarring at light throttle. Should I use the blocker rod or not? Thanks.


Probably not. You could try it. Not like it isn't reversible. But based on your description, it will likely be too aggressive for you.


If the results don't match the theory, change the theory.
