To keep you from posting this thread again when Ivan shuts it down, here's some advice.
1: After clicking search, type in either YZ250F OR CR125 (not both).
2: Change forum search to either "What bike.....", "CR,YZ,RM,KX...", or "Thumper". Not CR125 in "Thumper" though, or 250F in 2-stroke forum.
3: Click Search.
4: Browse threads for bits you can put together into a whole to give you a better idea.
5: Do not defy mods.
6: Do not refer to members as "snotty".
If you run into this situation where any member is telling you there have been many threads on a topic, but still you cannot find anything try to PM a mod for help. Do not re-post something. Don't take Ivan closing a thread so personal, he can be nice and helpful when you're not making him out to be the bad guy.
