Well the used 04 Wr I recently purchased has a problem. Seems to be not that much power. Started first kick everytime and ran perfectly for a week and half. The other day it was dying whenever I pulled the clutch. So at a stop light I was adjusting idle and it died. When Tryed to start it was smoke from under the engine could not tell where exactly, Had to move for traffic. Ifound the decompression rubber plug had fell off, put that back on. Now seems to run really really hot. When I get to destination and shut the bike off it leaves a puddle of milky oil. Did this 3 times and know it is parked until I get it checked out. My buddy gave me his yz cam, he put in a hotcam. So this weekend I am taking to dealership to have the cam put in and get it jetted,and looked over really well. I do not know that much about the engine stuff,YET. The guy I got it from just had vavles adjusted. I hope the motor is not shot. Anyone have a guess on what it could be? I do not want to put in shop then get charged 1500 bucks. If it is shot i will just blow it up then bore it. thanks.
