My son has a CRF150r which is leaking oil from the output shaft seal behind the front sprocket. Can I change that seal without opening up the engine? Any help is appreciated!

You should be able to remove the sprocket and lever the seal out. Installing the new seal will require a PVC home made driver to go over the spline shaft and drive the new seal in. Easy to do.
