Do Valve Clearance Specs change with YZ timing?
Posted August 16, 2002 - 02:02 PM
So my question is two fold...1) Do valve specs change if you are YZ timed?, 2) If not the valves, what is causing my engine to have such rattling noises (timing chain is tight enough I think).
WR manual has the following valve specs:
Exhaust: .25mm - .30mm (Mine register .25 and .30)
Intake: .15mm - .20mm (Mine all register .15)
Anyone know what the YZ manual reports for specs?

Maybe it isn’t a valvetrain noise. If you had a ’00 I would immediately holler, “CHECK YOUR CB KEY.”
But if it were me I would check behind the right cover for any signs of looseness (assuming I’d isolated the noise to motor-only first, i.e. makes it in neutral w/ or w/out clutch engaged).
