I just got a 92 rm 250 and it ran great in the 60 degree weather....took it out today (about 43-47 degrees) and it runs crappy, it loads up and doesnt have half the power it had in the 60 degree weather....could this be in the jetting??? Thanks

Probably jetting or air filter.

you will blow her up 2 strokes need jetted for different seasons. air like all other things expand when warm and contract when cold. this is the reason your bike is running like it is. rejet and then try it out .
