CRF250X.....Need Help



Just bought a clean 2004 CRF250X and was told by the seller that no mods were performed.....but when I got the bike home and removed the seat the air box mod had been done (top cut open).  I have no problem with this becaues I was going to do this eventually, but the only question I have is the carb and muffler are bone stock....can I do damage running the bike with the air mod and thats it??

Not really. Bike will run lean and hot as a result. That can lead to overheating, which can damage the motor.

Just take care if the jetting as soon as you can.
