Default Bottom end? Or what?

     

Okay, so I was trying to start the bike up (87 cr125) and adjust the carb (although I'm sure the carb needs to be re jetted now) and it makes a weird squeaking/whining sound when i kick it over fast. I starts 1-3rd kick but when its at low rpms it makes this noise and sounds like its something in the engine. Could this be a bigger problem? It seems to stop and sound fine at higher rpms.
Thanks,
Isaac

Sound like a bearing going bad. Maybe water pump or could be the mains. I would tear it down and replace all of the bearings if I were you.

Is there any one in particular? Any other possible problems?
How hard would it be to replace them
