    2004 CRF 450 Slip on Big Gun Race Tip

    Should I rejet the carb? Seems to run fine but this is the first 4 stroke I have owned had YZ250 before. I don't want to run this thing to lean.

    I am assuming we are talking about an "R". It should be jetted from the factory for a non-restrictive exhaust.

    That is not to say that it couldn't use a rejetting based on elevation or other factors, but just putting on a Big Gun slip on shouldn't make much difference.
