HOT CAMS Stage 2 Exhaust Camshaft for KAWASAKI KXF 450 2006-2008

On KAWASAKI KXF 450 from 2006 to 2008, the HOT CAMS Stage 2 2075-2E camshaft fits in place of the original part. Driven by the timing chain, the camshaft opens and closes the valves at the right moment. A worn or marked camshaft costs power; a new one gives the engine back its original efficiency.

Specifications

• Brand: HOT CAMS
• Manufacturer part number: 2075-2E
• Engine: 4-stroke

When to replace it?

• Lobes scored, pitted or worn at the tip.
• Valve clearances that keep changing, or timing noise.
• Marked camshaft journals, lack of lubrication.

Check the camshaft every time you set the valve clearance. As a Cross-Mania guideline, on a 4-stroke motocross bike this check comes round roughly every 15 to 30 hours; your bike's manual gives the exact interval. Replace the camshaft as soon as a lobe is marked.

Fitting tips

1. Note the valve timing marks before taking anything apart (manufacturer's marks on the sprocket and head).
2. Oil the lobes and journals with clean engine oil before fitting the camshaft.
3. Tighten the journal caps in a criss-cross pattern to the manufacturer's torque, then check the timing over several turns.
4. Set the valve clearance with suitable shims: a new camshaft often changes the clearances.
5. Replace the decompressor or its springs if they are tired.

Frequently asked questions

What does Stage mean?
Stage 1, 2 or 3 is a cam profile more or less aggressive than stock. Check the Hot Cams instructions to see whether your engine needs valve springs or other parts with this profile.

Do the valves need adjusting afterwards?
Yes, always: measure each valve's clearance with the engine cold and correct it.
