Okay, here's the deal. I took the stock exhaust off the other day, because my new exhaust was on its way. Well when I had it off I started the bike up to see what it sounded like with no exhaust. I let it idle for only about 30 seconds, and shut it back off. Now after putting on the new exhaust (slip on), it won't start! Would this have something to do with starting it with no exhaust (muffler)?
