Just a quick introduction! My name is Derek Marsden and I live in the Province of Gauteng, South Africa.My current BMW's are R25/3 which is fully restored, a R27 that runs but is in need of work, a R50/2 fully running and on the road, a R50US which is my current restoration project and is about 70 % complete and finally a R51/3 which runs but is next on the list for a complete restoration.

Can you offer a good metod for setting the timing on my R25/3. The method I have used is as follows_
Set flywheel in direction of engine rotation to full advance, open the weights on the advance /retard mechanism and set the points to just open. This obviously represents a static adjustment.

If you have any comments or better methods please advise.

Best regards

Derek

Howzit Derek,

Nice collection you got there! The other old mate of mine in Joburg with an R25/3 is Colin Wilson. Do you know him? Hes also a member of the VMC. Re timing, try setting it with a stroboscope. If you don't have a 6 volt stroboscope, attach a 12 stroboscope to any 12 volt battery, and the HT sensor cable clips onto the sparkplug cable of the R25/3. Put a blob of tippex on the flywheel marking so that it shows up, and you're away.

Hope that enough detail for you.

Best regards,

Mark
