All camshafts will offer their maximum performance when used with a professionally ported cylinder head and professionally cut valve seats.

Valve to piston clearance MUST be checked on ALL high performance cams. We recommend .060° clearance for both intake and exhaust valves.

What is the difference between a billet and hardfaced cam?
Billet cams are sold outright with no core required. They are machined in the USA and are specially heat-treated for wear resistance. Billet cams are used when problems arise in the hardfacing process of stock cams.

Hardfaced cams are made from stock cams. In the hard facing process, stock cam lobes are welded with a hard surfacing alloy to increase durability as well as provide additional stock for high-lift profiles. The stock cam (or stock core) can then be ground to almost any desired lobe shape.

Some models such as YFZ 450 prohibit this type of modification because cam journals can distort in the welding process.
