Vintage BMW Motorcycle Owners

on safety gaps since the systems sport copper core wires, logic dictates this gap is nothing more than a bandaid for poor ignition coils I've been told the replacement coils have modern and adequate insulation on their windings amazing is that safety gaps are quite conspicuously absent on most of th...

hard to doubt something one doesn't have an inkling of but I'd say it's safe to say they assumed owners would simply replace faulty ignition components with BMW replacements having correct electronic ratings heck, BMW didn't even go into any diatribes about rocker arm geometry confirmation after a v...

if it uses GM points that allow adjusting while the engine is running using a small allen tool on a flex shaft there are several condensers available for those point sets, that will indeed screw right in place, and they are available in a wide range or actual capacitance some of the points sets even...

straight forward requires an oscope, signal generator, and then an inductance meter makes it all handy however, back when I was a line wrench when points ignition still existed GM still had a box which would measure the coil and give a readout as to how many micro farads needed to be on the condenso...

one other observation regarding using just 'any ol capacitor/condenser' this particular circuit consists of inductance, capacitance, and resistance for kicks and grins will refer to it as an LCR circuit for it to work properly this circuit has to be balanced if it is not you will have metal transfer...

do you mean that the only timing adjustment is via the points gap?

if so

that's crude

they will work good and last a long time on just about any modern lubricant and that is certainly within reason when you consider the superiority of most any modern engine/trans/drivetrain lubricant compared what we would today regard as poorly refined sludge.......... aka engine oil of 60 years ago...

good to read that and nice work

a bump for some of the guys I've mentioned these engine bearings too hope some of you that see this may actually comprehend what has taken place and perhaps stir up some commentary register for the forum guys and if you aren't a member of the "club", the publication is a fine one even for ...

that's great they are working and working well assuming you properly thrash it and often what that tells you is the original design was over engineered the axles are very large as are the steering stems try a 300 series stainless axle on say a HD 45 solo bike's front wheel they are 1/2" and the...
