Swap over to a 41001 and the 9901 will become a monster and 9886 will be even moreso a monster........ My advice for a Legend 7 is a 9886/41001, 9901/41001, 9853/41001......you could also check out the 41032 manifold...... avoid the 41021 as the extra long stroke don't like it overly much, loses about 15 % power as opposed to the 41001
