I just recently obtained a 85 xl 350 r. my rockers are making a lot of noise. after adjusting the rockers to the point where you cant get a wrench on the screw and locknut . with out taking it appart i´m guessing that ill need new rocker pads and probably a cam. any ideas of what i should expect ? where is the best plavce to get all the parts that im going to need without getting raped by honda . this might be the time to plan for a hot cam and head work. any input would be greatly apreciated .
