Yamaha published one service book for the 2004 through 2006 Venture 600 sleds, and this is it: part number LIT-12618-02-30. The 2006 machine carries the model code VT60L, which is the number to check against the sticker on your tunnel before you order.
The same volume also documents the SX Venom ER and the SXVENOM, so the shared assemblies are covered once and cross-referenced rather than repeated. Sections run through engine teardown and reassembly, the fuel system, drive clutch and track, chassis and suspension, and the electrical circuits, with the torque values and clearances the factory specifies at each step.
Wiring diagrams and a troubleshooting chapter round it out, which is what you want when a no-start turns out to be a sensor rather than a carburetor. This is the book a Yamaha technician worked from, not a condensed aftermarket summary.
