Does the Cbr300r require a 600 mile valve check? I know they got rid of it on the cbr500R. The 13 cbr 500 had more then half of them needing adjustment at 600 and the 250 was only like 10 percent. The reason I am asking is because I am trying to decide between the ninja 300 which requires it at 7500 miles and the Honda. Trying to price out the better value.
