My owners manual says the wot RPM should be 5000 to 6000 rpm with 5500 being the best,a friend told me that closets to 6000 rpms should be the best who us correct?
6000 is fine but do not go much above that. The book says 4500-5500 but I have mine tweaked to 6000. I rarely run at WOT but like to have the extra speed for showing off.
