Just installed a Brocks Street Meg on a 09 Busa. Of course, the stock O2 sensor doesn't fit as we all know. Is it safe to run the bike with the exhaust on the bike and no corresponding map installed? I'm used to Gen1 stuff. I was told it was OK, but I just don't believe these guys! I'm told the computer will compensate, but I have a hard time believing that with no O2 sensor to read A/F ratio information.
