Today, getting home from the gym, while running on 3 hours of sleep, I put my carb back in my bike after getting it tuned up, and when I went to start it, I realized I FORGOT THE EXHAUST PLUG IN THE SILENCER! I kicked it about 5 times and was wondering why it wasn't starting.. I kicked it one more time and it started and ran for about 2 seconds then shut off. But I took the plug out and it started right up and ran perfect. The thing is, I'm a very paranoid guy, and I'm worried that I may have lost some compression from this happening. I never got the chance to drive it tonight and I don't have a compression tester.. Did this hurt my engine in anyway? Thanks! Btw, lesson learned: don't work on a bike while half asleep!
