Yep — this manual walks you through cam timing step-by-step for the Teryx 750 FI 4x4 (all KRF750 variants). It covers both cylinders with diagrams, timing marks, link counts, torque specs, and the tensioner reset. Ignition timing is ECU-controlled on the FI models (not adjustable), so the procedure you’ll follow is mechanical cam timing.
Quick gist so you know what’s involved:
- Pull the valve covers and timing/inspection plugs.
- Rotate the crank to TDC for the cylinder you’re timing (align the rotor/flywheel TDC mark with the case index).
- Set the cam sprocket marks level with the head surface (intake/exhaust oriented correctly) and route the chain so slack is on the tensioner side.
- Install/reset the automatic tensioner (compress, pin/lock, bolt in, then release).
- Torque the cam caps in the factory pattern/spec.
- Rotate the crank two full turns by hand and re-check that all marks realign. If a mark drifts, you’re a tooth off.
The manual will tell you the exact mark orientations, link/pin counts between marks, and all fastener torques, plus troubleshooting if the marks won’t line up.
Good luck!
