i see that this is an old post but it's the most info on xr250's yet. today i traded a $125 .410 for a 26 huffy trail runner and a xr 250. the reason; my 63 year triglycerides are up and my wife could stand some exercise herself. tomorrow is a complete tear down lube and adjust. thanks for the warning on the forks. gas and trans fluid works at times. gas carries the oil then evaporates. my trail is around a trailer park with speed bumps so i'm hopeful i have picked the right tool for the job. lol. and i agree with the maintenance idea, even a lambo needs fresh oil. thanks again.
