Thats o.k. well take the valve covers off and look inside at the valve train. See if anything looks broken or to loose. You can do a quick valve lash check by putting it in 3rd or 4th gear, put a pen in the s-plug hole and slowly roll the bike forward until yhe piston is at Top Dead Center. You may have to rock it back and forth a couple of times. When at T.D.C. try to rattle the valve rocker arm. It should have just enough play to slip a matchbook cover through it . Or check you owners manual for correct valve lash. good luck
