My muffler came off my bike ('04 ZX-6R 636) on I-4 the other week leaving me without a muffler. I ordered a slip-on to replace it but it's not here yet. I'm wondering if it will hurt the bike to ride it once without the pipe? My brother needs the car this weekend and I have a graduation to go to. I've read numerous threads about how running it without a pipe can cause it to run lean or possibly overheat the fairings, but they're referring to long-term riding with no muffler. Would it cause any damage to my bike to ride it once without the can?
