You might want to have it checked out, because I had some trannie problems after about 300 miles on my bike. It was a factory problem, the positioning fork was machined incorrectly and it made a lot of noise and would slip from first to second. They said it was a random problem and had no other complaints or issues, but who knows. They fixed it and everything is fine now, but there was definitely a problem (and it was completely covered under warranty). Happy riding...
