hey everyone, I am new to this site and would like all the help I can get. I know very little about dirt bikes and just bought a 97 RM 250 but I think I bought a junker. When I first rode it it oerformed great with no problems at all. When I got it home I rode it once and had a fefw throttle issues. When I tried to start it the next day I couldn't and when I looked in the transmission fluid it was milky white. I drained it and am pretty sure the liquid that mixed with the oil was coolant. It spits oil out the exhaust and I can not get it started for the life of me. Anyone know any tricks or tips that may help or what I will have to do about the transmission. I don't want to completly rebuild it but I think i may be forced to. Or I may look into a completly different motor and transmission assembly. Any information is greatly appreciated. Thanks a lot.
