Ground camshaft «J»

More power at mid and high revs for Street and Drag type motorcycles. These camshafts can be used with mechanical or hydraulic tappets, and idle remains unchanged up to 6,000 rpm with standard valve springs.
Camshafts designed by computer and precision-ground from alloy steel blocks on Landis CNC grinders
Adds more power across the entire rpm range and maintains a smooth idle
For less powerful Street-type applications
Direct mounting without needing to modify the cylinder head
Manufactured in the USA
It is essential to check coil bind, valve clearance, and valve-to-piston clearance.
On engines from late '77 onwards, the diameter of the camshaft journal, pinion gear and breather valve gear was modified. These components are not interchangeable with earlier models unless replaced as a set. Post-'77 gear sets are identified by a machined circular groove on the outer face of the cam gear.
