518 CAM / #1390 - Direct bolt in replacement for EVO engines, can be used with stock valve springs, pushrods and lifters. Will respond well with performance exhaust
and air cleaner. This cam will also respond well with increased compression and cylinder head work. RPM range 1,650 - 5,500. Grind: 518
543 CAM / #1391 - Requires performance valve springs, see FEULING # 1120 or 1100, performance lifters recommended but not required. Will work with factory
pushrods on engines with factory stack up, if deck height, cylinders or rocker boxes have been modified from stock then adjustable pushrods are required, see # 4091,
4077 or #4080. Increased compression, cylinder head work and performance exhaust recommended but not required, increased compression is required for bottom
end performance. RPM range 2,200 - 5,950. Grind: 543
574 CAM / #1392 - Wicked power band for modified engines. This is a great all around camshaft for engines with increased compression ratio, produces solid low end
performance and mind blowing mid and top end power. Extremely smooth cam lobe design creates smooth valve-train motion. Responds very well to modified cylinder
heads & intake manifold. Increased compression ratio, high lift valvesprings, performance exhaust and intake systems are a must. Performance pushrods, lifters and
clutch are recommended. RPM 2,350 - 6,300. Grind: 574
594 CAM / #1393 - Fierce performing camshaft for an array of engines sizes, larger displacement engines like 106, 111 & 124+ looking for a superior torque band with
excellent horsepower gains in heavy bikes (RPM 2,500 - 6,400.) Smaller high revving displacement 85-96 style engines in lighter bikes looking to twist the throttle and
tap into some horsepower (RPM 2,650 - 6,700). Large displacements respond well to increased compression ratio and smaller displacements will require it. 594 cams
require high performance valve springs, pushrods, lifters, carburetor and or throttle body work, performance exhaust, intake and clutch.
Requires performance valve springs, see FEULING # 1100 or 1200, performance lifters #4062, adjustable pushrods (see #4091, 4077 or 4080)
Feuling does not recommend tuning beyond stock emissions standards.
