jayball1 Posted April 13, 2010 Hi everyone, I have a 2008 530 exc and when I open the throtle fully the bike takes off ok but then seems to hit a flat spot like it is restricted in some way at the top end is there a simple mod I could do to get rid of this?. Also the book says to use 10/50 fully synth oil would it be ok to use 10/40 fully synth? Any help would be good Share this post Link to post Share on other sites
