T500 Ignition coil wiring question

Post by garncarz »

Greetings all,

Digging in to the old, cracked, nasty, misfiring ignition electricals on my '72 T500J. Can anyone advise which ignition coil (orange/white or orange/black wires) goes to the left and right cylinder respectively? TIA.

Basically, it the bike doesn't start after a rebuild, swap the plug leads. If it still doesn't start AND THE TIMING IS RIGHT, make sure the correct points fire the correct plug.
Think of how stupid the average person is, then realise that half of them are more stupid than that.

I have the coils sorted but she still won't rev smoothly. I have the static timing set properly on the left point, but the right point is too far retarded and I can't get it into spec with by moving the right point base. The manual that I have says that the entire points plate can be adjusted moving both points at the same time, but my '72 T500J isn't equipped that way. I am thinking that the rubbing block is worn and that replacing the right point is the solution. Thoughts? TIA.

A short term fix for the retarded points is to set the points gap wider than standard until proper timing is possible with the fine adjustment.
