    White smoke from exhaust on new to me 2004 crf50f

    by Daali » Sun May 27, 2012 5:17 am

    I bought my son this used 2004 CRF250F. Mods that I can tell it has are protaper bar kit and UNI filter.

    It has a bit of white smoke on take-off and if he is at low-throttle.

    I cleaned the air filter to make sure it wasn't oil from the filter. I changed the oil and plug, just because the bike is new to me.

    It still persists. Do I need to change the rings?(I have never done that before). Is there a walk through?

    How much smoke is troublesome, as can I get through the summer riding and do the fix in the winter?

    Thanks for the help!

    Well I don't think it is the rings anymore. Compression tests out to 165PSI. Bike runs very solid. I am guessing it is valve seals now.

    I'm going to do a little carbon clean up and see if it gets worse.
