There is also the airfilter box to consider. The right/left air injection tubes can be plugged with a timing aperture plugs. There is also a small hol...

Your scheme for the plug wires should work just fine. What I was trying to explain, in a somewhat clumsy fashion, is that with a wasted spark ignitio...

My understanding is that you should be able to use any spark plug wire on any coil tower. What I don't know for sure is what goes on with the ignition...

Richard is correct about selecting a desirable gear for a given speed. What I like to do is to keep the motor RPMs between 3000 to 4000 RPM and the se...

The airhead ignition is known as "wasted spark". In a "wasted spark" ignition set up, I don't think it matters. Wasted spark is when both cylinders e...

Your 1983 should not have an issue with the deleted circlip on the output shaft. That is a 1985 and later issue. It is possible to find a "false neutr...

When connecting a battery, I attach the positive lead first, ground lead second. That eliminates the potential for a spark when working with a wrench ...

That looks like part of a valve seat to me. The only way to assess just how bad things have gone would be to dismantle that suspect cylinder for a vis...

On early airheads, there is a parallel connection inside the STARTER relay that is employed to distribute electrical potential to the functions that a...
