Are the P11/N15 pushrods longer than Commando?.
Yes, up until the Ranger 750 which used Commando length pushrods/valves. Changing to Commando parts could be considered an up grade, in
in that it changes the rocker ratio slightly, and gives more lift. If you use Commando valve guides, then you can use seals.
