I am installing Pro Circuit T4 exhaust to my bike. Im being told I need to rejet when I do this. I've never done this before so no experience. Any help or suggestions? Thanks

welcome to CRF's Only! replacing the needle and jets is pretty simple. here's a link to doing this on a CRF450X (same principles used to replace them on a CRF230):

for jetting, consider the Power Up kit we offer. it has the power up needle and the jets needed to get your jetting spot on.

again, welcome!
