    Does Flame arrester change mixture?

    In the process of tuning my 93 SL 650. Since I have to tune it with the flame arrester off, to allow access to the carbs, once I get it tuned and replace the arrester, does it restrict the air flow and change my tuning?

    Yes, but in your case it only runs richer so you're safe. Just be sure to check your piston wash after 1 tank or so. Don't go WOT crazy till you check your wash.
