500 miles i believe is just fluids some light lubrication of cables maybe and alot of visual inspection,should have the details in the little book you got with your bike,but was never under the impression at anytime of any of the services,that they took apart your front end,now it says at a certain amount of miles they SUGGEST forks getting new oil and maybe bearings being replaced,but they dont just automatically do it..........unless you want them to...i was allways under the impression that this is why GOD makes it cold during the winter so we can do the maintenance on our shit......as for you BIG MEX i would do the service myself since you are capable,i have never taken my shit to a dealer so i can be charged $400 for fluid changes......
