WE CAN TAKE OUT THE BAFFLE AND EITHE JB OR WELD THE MUFFLER.
I DON'T KNOW ABOUT TAKING THE SHIM OUT THOUGH.

I USE AN OS#8. I CHECK THE COLOR AND CONDITION AFTER EVERY HEAT

ON RACE DAY, WHEN ITS CALM IN THE MORNING AND WINDY IN THE AFTERNOON, DO YOU RECOMMEND CHANGING PROPS DUE TO WEATHER CHANGES AND ON COOL MORNINGS VS HOT AFTERNOONS WOULD YOU CHANGE PLUGS TOO?

STEVE,
