03-09 should all be interchangeable the later models have a plug fix that might be an issues for the early xb's but it is suggested to update the plug anyway
oh and you can get them at buellster parts for around 40 after shipping
Wow...that was an insanely fast response to my first post. thank you. Left the battery in the bike over the winter and I heard that doing so might damage the voltage regulator so I was thinking of replacing it. Any comment? True/False? I am selling her and I want to make sure she is 100% ready to go before I do.
I really don't see leaving the battery in hurting the voltage regulator only possibly killing the battery itself. I would make sure the battery is good start it up and check the voltage while running as long as the voltage is good I wouldn't worry about it unless you are having another issue...
Good battery 12-12.5 volts
battery with engine running should be 13-13.8 volts roughly
Simple hook a volt meter to battery check voltage
start bike
does it make atleast 1 more volt?
if yes bike is charging
if no likely needs a regulator (send me a pm i have a used one i sell for less than Buellster
