Poor little 250's being abandoned everywhere. My son left for the Air Force in June. His 250EX has been sitting off in a corner of the barn ever since. He's coming home for Christmas so I thought I'd pull it out. The rear brakes are frozen...ordered new ones. The battery won't stay charged...ordered a new one. Twist throttle cable stiff...same. Poor thing, in five years it never skipped a beat. I think it misses having the snot beat out of it. It was even stolen and recovered, and you could not keep that thing down. I'll have it all fixed up for him by the time he gets here. I'm sure he'll whip on it enough to make it feel better.
PS Don't let your ATV sit, it makes them sad...get out and ride!
