RE: Tweaking TT .40 for max performance?
First... In AMA 424 I think the rules say "Box Stock" concerning the engine. So, no you cannot remove the baffle out of the muffler. Second, the 424 class has a max RPM limit of 16,500.... So if the CD does his/her job and runs all the motors in the morning and throughout the day, you'll get caught...
But. I like your enthusiasm..
