Anyone know the oil quantities for my 87 trx 250x? Seems to take quite a bit for no oil resevoir. Any manuals or schematics helpful also. Same deal for an 01 400 ex. 400 has a cooler, and oil tank. On the 250, it seems the case may take quite a bit of oil as the dip stick vs bottom of case is a good distance......thanks Thinking of possibly dropping a cr 500 motor into the 250 chassis this winter.....Just looks a little short and wheelie prone due to the chassis geometry. Anyone done this on a x chassis??? I have access to 250R chassis and parts. Thinking of possibly going with an extended swingarm on the x.
