[QUOTE="BSWIFT, post: 1213291, member: 16802"] Several possibilities. As stated, insure that your air filter is clean and oiled. Clean the carb and insure that it is seated properly when you remount it on the bike. Jetting is the most likely issue but you may have a gunked up power valve or acutator mechanism. Do a search in the CR/KX/RM/YZ forum under honda power valve. Also read the jetting thread that is at the top of that forum. The best thing about doing the search and troubleshooting this issue is how much you will understand your bike when it is done. It sometimes helps not to search real specific, eg:2001 CR 125 power valve. General searches bring up lots of information that is very helpful but not model specific. If you find an old thread that has more info but doesn't address your problem exactly, post in that thread and it will be bumped to the top of the forum. Other members can review the thread and likely narrow down your problem quickly because you have eleminated other possible issues. I've been on this board for many years and have learned a great deal in general about bikes but specifics are more related to yz's. A few searches will reveal tons of info and lots of insight. Good luck. [/QUOTE]
