Hey guys, i just got a 2003 CR85 and i love it! It has the stock muffler on it now, and i want to change it to a FMF Turbinecore II w/ spark arrestor. I think im gonna keep the stock head pipe for now. Do i need to rejet my carb with just a new silencer? I know this may have been talked about before but could someone tell me the steps on how to jet a carb or the link for a pervious thread? thanks again guys and i cant wait to talk some more here!
