2004 CRF 450 Slip on Big Gun Race Tip
Posted: Fri Jun 29, 2007 12:39 pm
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.
