Im about to pick up a 2012 honda crf250r but i do not have any previous maintenance history on the bike avaliable to me other than what is obvious cosmetically. It has an hour meter with 110 hours on it and by the looks of the clutch cover and stator cover that is for sure accurate but the motor and aluminum have no dirt staining like alot of bikes ive seen. It looks to be a very well maintained bike that a serious rider/racer owned previously though. It start easily cold and hot. Does not smoke or make any bad noises either. My understanding is that when a 250f reaches the 100 hour mark, a complete rebuild is recommended. This is the 2nd 4 stroke ive owned and im wanting to keep this one long term so i would really appreciate advice on the next steps i should take after i purchase the bike for my intensions of keeping it for awhile. Also im going to be racing hare scrambles in 250B so a fairly fast pace and also some mx here and there. I really want to put together the most reliable/ low maintenance build possible with this bike so im not looking for more horsepower, really just wanting to keep that close to stock and ill be happy. Any advice is greatly appreciated. Thanks.
