Where are the timing marks on the series 2 Jota?
I have removed the alternator cover but cannot find anything on the magnet rotor or the crankcase face.
Some pictures would be mighty helpful.

 
Simon you should make your own marks but the reality is if you are using the original Bosch ignition they are something now that is quite a compromise for your engine.
I cant remember what the full advance was but I am sure it is somewhere north of 32 degrees I believe the advance at idle speed was either 8 or 10 degrees.
So if you do some simple maths work out the circumference of the circle where you are going to place the marks you should be able to identify those two points, I think the full advance hits somewhere after 3000 rpm.
Or you could junk the whole ignition system and install something that will transform your bike and be easier on your engine.
 
I have fitted a Sasche Ignition System and got the spark.
Looks like I have to use a piston stop to establish TDC which I can do of course.
 
Simon a piston stop and degree wheel will get that perfect TDC but if you are patient you can closely estimate that position to get started.
Once TDC has been established the Sachse should do the rest for you so unless you want to cross check what its doing don't worry too much about timing marks.
 
Series 2?
Alternator cover?
Ignition is on the left on a series 2.
