You got it. "Rocker covers" is an ancient reference to what is commonly known as valve covers. Cam caps hold your cam in place.

INCH POUNDS

FOOT POUNDS

THEY ARE DIFFERENT.

problem....

Ill post the pics from working on it later but i have a problem. Look at the pic. (that pic was taken with key out) The temp gauge goes from the line after the middle line to the tip of the triangle. and goes back and fourth constantly. also From a cold start from sitting in the 60 degree weather for four hours it only took the length of a football field st like 3000rpm for the temp gauge to go to the middle.


Maybe its because i didn't bleed the coolant lines? or something. all I did was pour it into the radiator. It burped a few times. This was from riding at 45mph at 4500rpm in 60-70 degree weather. Also my radiator fan does not work. when i put direct power to it, it works. so it must be the relay. i also cleaned grounds. but regardless it shouldn't get that hot without the fan going. And help would be greatly appreciated

I suspect a bad connection from the temperature sensor. Go there and check all connections. It may be a short against something, but usually, a short will send the temp gauge to the red side pegged. As you just had everything in that region apart, I would venture that there is something not making a good connection after re-assembly. A bad connection would also interfere with your fan.

Here is a link to a wiring diagram for a KLR 250:
