I just got back from two weeks in the UK, and hopped on the Bandit for a ride.
I had no problems starting, although it did take a long time to warm up, but my bike sounds noticeably different. It's like there's an extra, higher note to the normal throaty noise the engine makes. Kinda like a two note chord adding a third note.
I'm not sure if it's caused by a different pair of earplugs, the weather, or something gumming up during a two week stint parked in a garage. I'm going to switch back to my other earplugs and hear if that makes a difference.
