Well I recently rebuilt my bottom and top end in my 02 CR125. It wasn't too bad, it took a few weeks, as long as you have the correct tools and a service manual, you shouldn't have too much trouble. There are some special tools you will need to pull the cases apart, and those aren't too cheap. Just take it slow and don't rush the job. Take it one step at a time!

Buy the service manual and read through it carefully until you understand each section of the motor rebuild,once you read that and understand it you should be able to make this decsion for yourself better then anyone else could do for you :cool:

i am getting ready to rebuild to bottom end of a 99 rm 125 and have never rebuilt a 2 stroke a few 4 stroke though, but i was wondering how many specialty tools did you need and about how much did they all cost, (trying to figure out if it would be worth the time and money to do it myself)?
