Static Ignition timing for 1977 YZ250D and YZ400D
« on: October 17, 2013, 04:04:48 pm »
As the title says, I'm just looking for the static ignition timing for both my YZ250 and 400 D bikes.

Anyone know what it should be or could point me to a reference manual or similar?

TIA
Craig

Don't you worry about bike timing you just get alcohol/ bike delivery times in sync ;D
