New here and hope to learn from this forum. I have a 1993 RMX 250 roller, 1993 RMX 250 complete runner, 2015 DR650 I ride a lot and a1989 YZ490 basket case, fire damaged wheels, frame, seat(disappeared in fire). Not sure what to do with the YZ490, maybe dirt drag/hillclimb build or put the engine in the RMX roller. Already sat it in the frame to check fit.
