dont start it without changing the oil. I would check to see if the carb needs cleaned .the needle and seat could be hung open with dirt or something. If so it can fill the motor with fuel.Did you leave the fuel on,off and reserve switch on for to long when not riding. well change oil then check for compression.the top end could be letting the fuel mixture blowby.

They should be close enough to use, might have to trim a little to get an exact fit.
2004 RM 125 Head Bolt Torque is Initial 11 .0 lb-ft, Final 18.0 lb-ft
These (link below) are for a 08 RM 125.
Its stamped on the Crankcase and its 850ML.
32:1 ratio
Stock the claimed hp is 40 hp.
I believe mine says 800ml on the side of the cases. Or it should be a little over 3/4 of a quart.
Will a 94 rm 125 engine fit on a 2000 rm frame?
A 1997 rm 125 can go around 60mph.
