Alright check this out. I just got back from the dealership where I bought my bike. I rode straight back to the shop. First off, the head mechanic acted like it was a pain in the azz for him to stop working on his personal bike to talk to me. Every time I go back there, the head mechanic is working on his kids dirt bike. Anyway, I asked him about the fuel mileage and told him I was currently getting somewhere between 25 and 30 MPG and he just stared at me like so whats the problem? I told him others were getting 45 and even 50 MPG. I asked him if it would get better after break in and he said not that much better, maybe a couple more MPG. I asked him why there was such a difference in fuel mileage between the same model bikes, and he just shrugged his shoulders and said that is just the way it is. About 100 miles per tank of gas. Needless to say I was not satisfied with his indifferent answer. I don't believe there can be that much difference between the same model bike. From other posts I have read here, the above indifference seems to be the status quo at Yamaha dealers and their service dept.
