CRF150R Jetting? by joegencon » Wed Dec 27, 2006 5:41 pm
Ok question here ive been told to rejet my sons 07 CRF150R with a 140 main and a 45 pilot. The bike is so loud we bought the DB Dawg silencer insert for the stock bike. Otherwise the bike is strictly stock. Because of the silencer should i drop to the 138 main or stay with the 140?
