KLX140 Stage II Camshaft Kit with HD valve springs and roller rockers.  This camshaft works great throughout the powerband and is more suited to bikes with the 170cc big bore kits installed.  If you have a 170cc kit in your KLX140 this is an excellent upgrade and boosts power!  Kit includes the camshaft, HD valve springs, roller rockers and a new set of cam bearings. 

Please note: You need to grind the two areas shown in pictures for clearance on the rocker arms.  It is easy to do and only takes a couple minutes with a die grinder.
