RD400 Two Week Rebuild

Grab a cheap HF dial gauge and pop the heads off. Use a head bolt plus some angle iron to hold the gauge on to of the piston.
Grab a small 12v bulb and holder from an old speedo/tacho/idoiot light and attach crocodile clips to both leads. Attach leads to ground and to the coil to Dyna lead and turn the ignition on. Rotate the motor and see when the light goes on.
When the Dyna is "closed" the power flows through the Dyna module to ground and when it "opens" your timing light will go on. Adjust as required and repeat on side 2.

BTW, reeds don't make much of a difference if any
[/quote]teazer its a 30 something year old piece of harden steel that bends for a living replacing them with any thing that is not steel is always a good idea. Ever see what a broken one will bo to a crank case.

That's true Brad, but they rarely break on street motors unless the reed stops have been bent too far or removed -and then they do break off and wreck things.
Damage to crankcases is also not often a problem but if they go through the ports it can get ugly.
