Ignition timing Apologies Howard. Perhaps if you're plodding… Perhaps if you're plodding around a town or city and keeping a high gear then accelerate and get some pinking, a little bit retarded may work. Timing the right way Hello first thing is to remove the tank and then the rocker covers to find TDC on the right stroke making sure the Magneto's points are looking up to the battery box you should find were the ring cam closes the points this is for the left hand cylinder the ignition lead is the back of the mag next to the battery box the nearest ignition lead is for the right hand cylinder you the find TDC with all the valves closed then fit the timing disc and pointer and turn back the piston to Richard Forsey Jul Gregorysimpson at gmail.
It was completely overhauled roughly 10, miles ago, and everything remains in sound working condition. Thu, 01 Feb fscmaui at gmail. This motorcycle has been set up by the previous owner in race with big carburettor, big narrow front wheel, big petrol tank, big brakes, Brookland exhaust, Bike is 2,20m long, Brakes , gears , clutch are working fine A real driver for both, the roads and the race track.

Most coils will have become warm in their life and with that the Shellack degrades.
A tell tale for a coil gone "to meet its makers" is that it feels a bit "soggy"when you pinch in it. A good coil with a chance for being still working, should feel rock hard. Most coils however feel soft, indicating that the Shellack has deteriorated and partly migrated from the place it should be.
In some magneto's you can even find blots of shellack sticking to various parts of the static internals of the magneto, where it has become so soft it was thrown from the rotor. Another tell tale of a bad coil is that a motorcycle starts OK when cold, but becomes very hard to start when hot. Due to the softening of the Shellack, windings short circuit and thus reduce the "power" being generated in the coil leaving a weak spark to do the job.
There is only one cure for this and that is to have the coil rewound. Nowadays that is done using very good temperature resistant epoxy resins virtually making them indestructible for the rest of your life. These were also never designed for an eternal life and although they might still work, you have more certainty by replacing them with more modern equivalents. The spark between the contact points should just be a tiny and hardly visible in daylight.
The ignition timing settings are a bit confusing. Depending on the source there are rather different specifications. This all shows that the actual timing is less precise then some people think it to be.
Its my guess that this is basically because it is a mnaully controlled operation. A precise setting can be totally ruined if the handlebar control is abused! Setting of ignition timing :.
Here you can find two ways of ignition timing. One as given by Lex Schmidt and based on years of experience, the other the original factory proposed way. Its up to the reader what to follow. That should do the trick. At the fully advanced position, this setting will be slightly early compared to the original manufacturers setting. The higher octane number of the petrol does make this possible. You can change the lever setting such that the engine runs properly.
Factory instruction:. CarbuRation For people not having acces to all information I hereby show the pages from the pre-war maintenance manual showing the settings of the carburetter. Setting of ignition timing : Here you can find two ways of ignition timing.
Lex states: This is what I always do and it can hardly go wrong. It works because of the higher octane fuels as presently available and you don't need to measure anything. Especially handy when timing overhead valve bikes without a hole to measure the piston position.
