crf450dirtboy Posted October 2, 2005 I have a 2005 CRF450X I put in a twin air filter, and I pulled the baffel out last weekend, I am curious if I need to rejet or anything. I have no experience in rejetting so far. I am wondering if I need to worry about burning up my valves. Thanks in advanced! Share this post Link to post Share on other sites

Alaskan_h230_gurl Posted October 3, 2005 I am 450's wifey. No he has not yet, because he is concerned about going through rivers, and deep puddles. Share this post Link to post Share on other sites
