Thanks everyone..........now I will go back to the Forum page, search for Batteries and see if anyone has posted about how well the battery holds up on the WR450's. As mentioned, I bought mine brand new just last Monday. As of yesterday, the battery would not turn over the electric starter. A bit dissapoining I might add. The batteries hold up very well in these bikes. I am still on the original batteries in both my WR's. I suggest you take out your battery charger and recharge it. It should be fine.
